What a great video. I have Parkinson’s and I need to develop new skills to help my brain. In spite of the tremors I think I’m going to try this… Thank you so much for fascinating videos on a hobby I’ve enjoyed for almost 50 years (Hi-fi audio… Not building stuff!) Thanks again!
Ralph that's great to hear! Keep me updated and feel free to reach out if you need anything. Good luck! And thank you for the kind words.
123Toid I’m serious, you have a very sincere And informative delivery that I really enjoyed. Keep doing Just what you’re doing!
And so, did you build it?
maybe invite a friend for the difficult small parts
Hope you are still enjoying the Hi-Fi Ralph. I am an engineer of near enough your age and have worked in audio for most of that time. If you ever need any advice or help just drop me a line here (I will see it it).
Thanks for making this tutorial. It took a lot of time, and a lot more work and money goes into this than most people realize.
300$
What a fun project. Looks like something to do this spring! Thanks
I just finished assembling this amplifier, it went well but a few wire colors have changed in the new kit. It passed the startup "smoke test" and it has noticeably better sound then Yamaha receiver it replaced. Love that it does not have a fan. I think the kit from Ghentaudio is worth the money, well organized and nicely done. It would make things quicker if Quentaudio came with some basic instructions including a wiring diagram.
I was thinking about getting amp from Peachtree they use ice amps and I was interested in building one do you need a pre amp with that and he doesn't show where to solder I wish he showed more . How did you figure out how to wire it up ? Thanks
@@BostonMike68 No preamp needed, I have used a DAC or my Phone as an input. I had to watch the video several times to figure out the wiring, fairly simple in once you do it. I could send pictures of my finished amp just not sure how to get to you.
I got my summer project. Thanks!
Hey ? Did I you do your project. I was wondering bc I’m thinking of trying to do one.
Thank you for this video, sir. I was unclear exactly what to buy visiting the website. You made it all clear! I have an itch to build one of these now.
I just got done building this amp last night. And WOW does it sound good. Your video was a big help. I'm using the amp with the Pro-Ject Pre Box RS that's a true balance preamp with tube output, speaker are Merlin TSM sealed monitors. Who would think spending $300 would bring great sound. I'm a happy camper!
Oh man you have the merlins? They reveal everything. God I miss those. RIP bobby
Do you need a pre amp
thank you so much i love building things your videos and plans are great !!
Video was very helpful and products recommended 100% met my needs. 2 channel amp is just the beginning. Need a 12 channel for my entertainment center.
De-pinning/re-pinning would be your friend in this instance. It would make wire matching a bit easier not to mention cleaner inside the case. Second, in the immortal words of AVE "Focus you Fak"
Today in this video, I'm going to show you how to build an amplifier. 75% of video out of focus.
It would be easy for Ghent just to make a wiring kit that already has these interconnects pre made, since they know they're going to be selling tons of these specifically for the 200ASC and 200AC modules. This way no soldering would be required at all.
@@Wizardofgosz But then folks that don't know what they are doing would get in over their head. Consider the soldering requirement to be a barrier to entry.
@@jameshisself9324 This build requires soldering either way.
@@Wizardofgosz Well then more or less soldering then.
Very cool, and informative video! Thank you for the enlightenment.
Just finished this build. Excellent amplifer. Wouldn't of happened without this video. Thank You
So glad to hear this. I’m glad you’re enjoying it.
I feel like ive just opened up my favorite new wormhole of sound possibility. Couldnt have made it look any easier!
its natural smooth and unintimidating sound very refreshing, actually rare in market full of ciems and headphones
Oh, this is tempting!
Wish we had more teachers like you ( Toids diy audio ) back in the day, thank-you sir !!
Just built this amp. Thanks for the video! I wouldn’t have tried building it without your help. Now I need to build a Bottlehead preamp so I can try it out.
Awesome, much appreciated. Making me feel like I can properly build this type of stuff!
I think it might even be possible to do a three module system with the third one used for a subwoofer amp with the low pass filter mounted internally. Whole concept has many possibilities.
Subs often require alot more wattage from my experience. I often just give up and go integrated lol. Subs are more muddy anyways, I'd rather focus my efforts on the midrange and tops
Thank you for the info. it is very helpful 👍👍👍
Well, that's very much appreciated sir, thank you I'll have to look at video again not as familiar with being successfully hands on building or repairing amps, but I have had experience with diy speaker building since high school and I'm north of 40 now. I really enjoy things like this so thanx again keep it coming!👍🏾👍🏾
Your welcome Jeron! Have a Merry Christmas and Happy Holidays!
Oh man, what a great video. I did not even know you could build your own amp! I'm definitely going to have to delve into this as a new hobby. Thank you for the instructions!
You're welcome! Glad I could bring it to you.
You can definitely build your own amp and you can DIY way more than this. There's nothing wrong with this little set up but if you wanted to be nitpicky it's not really building your own amp but more like putting together all the main pieces of an amp. It's what a pre fab double wide is to actually building your own log cabin. An even more hands on approach would be to hand pick an amplifier chip from one of the manufacturers and then search out a board for it and personally select and order all your capacitors, resistors etc. Even more hands on would be to design your own discrete transistor amplifier and have your own pcb customade by a board house,. The possibilities are endless. One could spend their entire life dinking around with diy audio and not even scratch the surface of the possibilities
@@jethrohetero4990 You'd need knowledge in electrical engineering, I assume?
@@michaelhenry3234 not necessarily, I guess you could call it that but you don’t need to know the whole scope of electrical engineering. I mean if you were going to design your very own discrete design and pick all the transistors yes you would need to know quite a bit but there are lots of simple great sounding amp designs on the web that the amateur can build. There’s a quite famous one called the jlh 1969 amp that sounds fantastic the schematics are all over the internet There’s a bitching single mosfet amp Called “le monstre” designed by Jean Hiraga and there are also a ton of chips that only need some capacitors and resistors to make work. It’s great fun really if you like hobby electronics. You can etch your own PCB’s or order them from board houses for pretty cheap
Back when I was a tweaker I’d spend hours geeking out on honemade amps. Now that I’m sober I’ve been wanting to have another go at it and see just how impaired I really was. I bet i could whip one up in no time with nowhere as many mistakes as I used to make
Fantastic thanks and subbed etc
Nice tutorial man! I really enjoyed it. I think I might have to try this project out. Have a great one!
Thanks Man! I hope you enjoy it if you do tackle it! As always, good to hear from you.
I am blown away thanks !!
Small problem. You're going from balanced XLR to unbalanced RCA. You cannot simply tie the + and - together as one lead with ground (or shield) and if you only use one side you're only getting half the signal. The only way to do this right is to use a matching transformer with one side having a center tap, which would connect to the XLR ground and the other side without the center tap going to the RCA. Not doing what I just explained will result in having to have a much hotter signal, which can create other problems. I've been to this rodeo with my PA equipment. Just passing on the tip
Great point
even if this is a manual how to asemble this amp it"s still a good video,thank you a lot
Hi, cannot yet figure it out. Going to try; I did so with my desktop PC of 2003. I upgraded to Windows 7 from XP, and I installed an extra hard disk drive. Thank you for this detailed, and comprehensive demonstration.
yes this is what i have been looking for
Very good, i built this entirely from the links, parts and steps detailed in the video.
What would people recommend as a dual gang Potentiometer between the source eg: phone/dac/computer and the amplifier for volume control?
Was thinking something like an ALPS RK271 dual gang potentiometer 100Kohm, and a capacitor 40nf capacitor?
I want to see you use both of these amps and a diy 5.1 preamp kit along with a asp 1000 and make a 5.1 with a 1000 watt subwoofer output
That is a good idea.
Very impressive video I thank you sir my compliments to you for the knowledge you simplified the build very well
Excellent bro. Keep up the good work 🙂
Great video. I have also built several Icepower amps using similar components. I had not done this type (2 modules) so I have ordered the parts for this one. You did a good job and answered some questions I had to guess at since there are not instructions on the net.
For those that think they know about Class A/B/D amps and are throwing jabs at this build, you would be wise to do some research. Respectfully, you don't know what you are talking about. I have built several Icepower amps like this. I have modified PS-Audio amps that do indeed use these modules. I have built Class A low watt amps such as the Amp Camp Amp designed by the legendary Nelson Pass. There is also copious documentation about the Icepower amps that you can easily google for details about distortion, etc. I would caution someone to actually listen to these amps rather than just jawbone about measurements.
Again, this is a very good and helpful video for the DIY audience and I give it a very high recommendation.
I would go hear them but there is nowhere to go hear them because they are sold online only. He is receiving money for every module sold through the link in this video and should show proof they stand up to the specifications that he states they have with an audio spectrum analyzer and some math
@@waderyun.war00034 -- The guy's a hobbyist helping other hobbyists, not a professional engineer with $100K+ of fancy test gear at his disposal. Moreover, how do you know he's "receiving money?" Neither Parts Express nor ICEPower are Amazon, and AFAICT neither company has a link-for-pay program -- that doesn't mean they don't, but I certainly haven't heard of any such arrangement for U-Toobers.
@@editorjuno those links are what's called affiliate links and for every item sold through them he will receive compensation. I don't know how much probably almost nothing but he will receive something. Like I said I haven't heard a class D amplifier that sounds very good but most people can't tell the difference anyway for some reason I can and have always been able to. My friends would show me their sound systems and turn them up all the way and would ask me if it sounds good and I would have to turn it down below 3/4 of the volume . Then ask them if they could hear the point where the distortion went away and they couldnt
@@waderyun.war00034 -- Is this something U-Toob does automatically or does it have to be prearranged?
@@editorjuno his is through commissionjunction.com not sure if it's pre arranged or through CZcams
Thanks for sharing. This was a great tutorial. I still wish I was your neighbor
Haha, maybe someday :D
I just want to say as s subscriber from when you had only a couple thousand. Your editing and format has come a long way. Keep up the good work!!
Thank you. I have really been working on that. So I appreciate hearing that.
Sometimes it's interesting to hear what or why people are visiting your videos... In my case I Just opened a pair of NOS KLH Rave CB8 Speakers today. There's something magic about a 3 way with dual horns. The last pair of these in existence I am sure. Super rare. Only 1 amazon review... from 2005. I can't crank it because sleeping family but the sensitivity is 92db... they take more power to control them than I want to put in right now but even at only a watt or two driving them they sound amazingly accurate. They claim to handle 300w so I am here to build me an amp!
Great video, looks like a fun project! I have a few amps and believe comparing this to a $3k amp is a far stretch. However, for what the parts cost I think it is a good value.
Why? There is a lot of cost goes into, design, manufacturing, advertising salaries and ofcourse shops also add big percentage of that cost, and here you paying just for the parts, for me it makes sense, for person who has bought very expensive amp should not probably :D
i'm guessing his point is that someone, somewhere, is selling a version of this for $3000. might not be the best $3000 amp out there, but a huge amount of the hi-fi market is based on how well you can present something in a showroom and speak in appropriate hushed tones
Interesting. BTW, the link to the 'zoomed out picture of the internals' is broken.
Nice build brother !! Good content !!
Great video!
When i read "How to Make" i was kinda expecting to make it from skratch , but still a thumbs up, it was over all a good video even though it was different than i expected
Thank you. I appreciate hearing both comments!
The one thing I would recommend with these units that use balanced xlr inputs is to ground pin 1 of the xlr to a case ground point as close to the xlr as possible, say one of the mounting screws for ex. And ground the shield coming from the board to a different point on the case. This reduces potential ground loop issues and the possibility of inducing noise into the signal chain, especially when using rca to xlr cables like the ones shown in this video. This also has been covered extensively in AES48 specs and documentation by hypex, Rane.
Hi which site do you recommend to purchase the balanced XLR inputs?
@@user-cr6ki4qs4y The Ghent Audio case he is using in the video comes with xlr inputs. I believe they are Neutrik.
@@aredd92 thanks
I'm not sure if it will work with the power button setup you have, but I bought a Ghent case that uses an LED status indicator and a rear power toggle (no push button power switch), and I was able to configure it to automatically power on and off. Instead of using the mini jumper on J4 (power always on), I jumped J3 input 4 (signal sense) to input 8 (+ audio in) at the XLR connector solder tab, and the amp turns on and off automatically when it senses a signal from the DAC.
@@BuckStrickland-yc3czTo be fair these Amps are incredibly efficient and the standby power is minimal especially when compared to an A/B amplifier. I wonder what the real word energy savings are in your case?
Thanks for the video...
Just WOW!
Toid you are a god, your format is great and you actually know what you are talking about. These videos are a huge help
I am still using crown amplifiers and love them no better clear live sound than from the crown D series of the 70's
Thank you for the awesome videos. Is the wiring the same on the 1000 amp model? Is a low pass filter needed to run a sub if my signal is coming from the sub output of my denon home receiver?
Great timing, I've been looking to upgrade from my old parasound, well maybe not upgrade but something different.
Keep the parasound, It's better.. This is crap !
@@JasonLeaman yeah I'll keep the parasound. But for a few hundred buck I'll also give this a shot to see if it is "crap"
I do have already 2 mono class d amps - 200 W each and indeed they sound good. Not lce though.
That's true, ICEpower is amazing lots of my bang&olufsen products use it. But standard class d is also really good
Any idea how to add a gain knob to this? For my setup this would be used for the bass bins, and I want to manage the amplitude differently in day / night quickly. Thanks for the video!
Just add a preamp with volume control
Ive been wanting to make a good quality class D amplifier for a home subwoofer that had its board die, and i lost it before i could fix it. This would really help me set it back up and get it running without having some cheap homemade amplifier that barely outputs power. I didnt want to buy one, i want to expand my electronic skills and try to build one. You sir have made this possible. Thank you.
Yo' Geof Schnider from PE give this guy the more powerful versions of the boards 500w/1000w so he can make some more cool videos on this great topic
I built this amp and have been running it with a Douk P1 tube preamp and it sounds great! Is there a way to run this amp bridged? I'd love to build another and run them as mono blocks.
There isn't a way to bridge these. However you can just use one module for a monoblock. If you want more power, you just want to go to the 500 watt, which I linked in the description.
This video has convinced me to try to build one of these amps! Question...do you think building this amp would be easy enough for someone with only the use of one arm? (the other recovering from surgery)
Thank for share man
You're welcome!
Great build buddy ❤️
At this same price, you could have made a 3000+ watt amplifier in our country. Which produced a very sweet sound and a terrible earthquake bass.😊👍
Great video, I'm definitely going for my first DIY project! Do you think this setup of one 200asc and one 200ac is equal to dual mono (2 boxes with one 200asc for each)?
I've never tested that, but there's no reason for me to think it wouldn't be. They designed the power supply to power three modules. I've never felt it was underpowered either.
Thanks for sharing
Really enjoyed this video. Definitely plan on doing this soon. I am curious if you know of any cases for amplifier projects like this that are rack mountable? I have been doing a bit of research but mostly have only found cases that are completely raw and all the holes have to be made yourself, which is fine, I am just curious if there is something better already out there.
Unfortunately I don't know of any that are specific to these boards. So you'd have to buy a raw board and make the holes yourself.
When attaching the ground lug to the case I think it may be prudent to sand off the finish on that part of the case to get a better connection. I am looking forward to building and testing this amplifier. Thank you for the video. With tax and shipping so far I have paid $360.80. No word on tariffs for the case yet.
Great call. It definitely is. My case already was sanded down. My assumption was they all come that way. Hopefully they do.
@@Toid Now I just need to hurry up and wait :)
Just finished the amp. I am very happy with the sound and it is as good or better than my class AB Rotel 981 Power amp (1990's). - Thanks for the video; it really helped a lot. I did a few things differently like the grounding and repined the sockets. Looks like it compares with the PS Audio S300 that uses the 300ASC and 300AC. So; for $360 I get 2/3 the power of Paul McGowan $1500 power amplifier.
@@BriansModelTrains that is great to hear!
I’m wondering if this is a better option than proven class D amplifiers like the Crown XLS series? I mean DIY is a win on this but bang for your money, what’s best?
I really love the crown xls amps
I just grabbed the crown and I love the extras you get with it for around the same price. You get crossovers leds ect ect
That's a very good question -- although Crown's customer base is mostly pro sound folks and DJs, AFAICT their amps are certainly well suited for home audio systems that need lots of beef to handle volume peaks too. Of course the "audiophile" crowd will dismiss the XLS amps as cheap Chinese-made junk, but I honestly wonder if they could tell the difference between an XLS and a PS Audio Stellar amp driving the same speakers at the same high volume.
Crowns have some what higer noise and distortion products, you can check ASR fórum for some nice measurements on some icepower based amps and at least one class d crown, i think it was a 2505 or some like that. Ice amps excede the total signal to noise by some 10 db diference aproximatly compared to crowns, true the second delivers More power per dollar spend
Also look at the 3e Audio 3255 board and matching power supply.. great class d chipset, v good sound and build quality.
Haha! You use wrong words when you talk!
Me too...
Great video and channel. Subbed.
please done a sound test review video of this amp
Thank you for taking the time to build these amp. Don't have much experience with class d amps myself. I wish more videos of building amps existed. Have you considered trying to build a low powered class a amp? I purchased some of nelson pass diy amp camp amps (their are version 1.6 now). They put out 6 or so watts of hot class a from the single amp and more out of the new mono version (one for each channel). A little over $300 for each kit when they go on sale. They sell out fast each time at diy audio. These run on cheap switch mode laptop (24 volt) power supply and sound Fabulous! They will even sound better with a proper linear power supply. More $$$ to. Just keep in mind these amps need to be used with efficient speakers (90 db and up). Even better with higher efficiency speakers. Just a small taste of the that legendary nelson Pass (pass labs) sound for not spending thousands. And if your wanting even better amps and wanting to learn more their is the diy first watt f5, j2, etc that offer even more😀 thanks for sharing this build!
I'll have to take a look into that
@@Toid your welcome. I'm not sure which batch will be shipping out or when but I think you can given them email to notify you at diy audio when next batch is available for purchase. Just a heads up..each batch sells out fast. I have missed a couple not being fast enough lol. It would be terrific to see another video on assembling one of these kits. One video exists online of them putting together a older version of this kit together. Those were 2 little mono amps. Can't wait to put my amp camp amps together. Need to get time and a soldering iron😀
I tried to build a stereo amp with a toroidal and 2 tda boards. Never worked, just left it to gather dust :) this gave me the motivation to troubleshoot it.
Great to hear!
Hi. I have a home-built stereo Wadar amp using tubes and that sounds great too!
Nice!
10 million fkn points my friend. for saying "solder" instead of "sodder" .,.,thumbs up :)
Hi, Just want to confirm that i get it correctly after watching the video, so, i need to buy 1 X 200ASC board and another 200AC board to connect together for a stereo power amp ?
That is correct. You can actually buy another 200ac board if you want to make it a 3 channel amp. All the links are in the description to all the parts that work together. You do want to get the cables to hook it up as well. Unless you're going to make your own.
@@Toid
Just a minor heads-up, but at the start of the vid, you referred to the ASC as the ASP, and the AC modules as AS.
Do they have alternate part numbers, or was it just a mis-speak?
@@electronash at 1:30 I answered that. Basically I misspoke.
@@Toid
Ahh, see, I made the usual mistake of typing before watching. lol
Fair enough. ;)
@@electronash haha, no problem. I knew it would get some people, so I tried to do a PSA. But I know, not everyone will see that. Glad I could help you on the confusion.
A demo of the device would have been real nice. Didn't know we could get these kits. Real nice.
Congrats on 18k
Please send it to Andrew Robinson for review against Crown XLS!
Crown is fine...
Nice! Add another project to the list😁
i found a used diy poweramp with a design like this a year ago, dual 200 asc for 2x100watt stereo in 8 ohm typical.
im still learning about what i actually got, it runs cool and silent and sounds good. hopefully i can find more reviews comparing those amp boards to other prebuilt brand poweramp counterparts.
only gripe i had was the auto power on sense was turin off my amp at low volume after less than a minute. but i got around that with opening up the case and bridging 2 pins so it was always on. with diy amp boards you can get proper schematics online so i could figure it out, much harder if i had a brand name poweramp.
Can I plug a DAC like the Schiit Modi 3 directly into this amp? Or will I need to run it thru a Pre amp? What are options for powered sub connections?
Thanks. But what about speaker protection ??? Is it inside the amp board ???
The best protection for your speakers is to not buy/build this. Irrespective of whether it's good or not, this CZcamsr's bullshit clickbait and amazing levels of ignorance are reason enough to avoid it.
is there dc protection ? or should i add input transformers ?
Can you explain your question? I know nothing about electronics. Why DC is bad and why you question need of transformer and what transformer will do to DC to make it safe. Thanks.
Scott Johnson DC current on the input or output will likely fry the amp or speakers.
Using a transformer will isolate the DC power, since it can only work in AC (sound is AC power, with variable frequency between 20Hz and 20.00kHz)
@@radusimonica5550 sound is actually DC not ac, ac is whats in your wall socket dc is what comes out of a guitar into an amp
what would be good if you could build a retro style preamp. bass, treble, loudness contour or switch. volume control. mc/mm preamp built in. line in and pre out.
Great Job. Always wondered how you could build one. Seemed like parts express was missing some stuff.
Yeah, it is awesome that they finally started carrying this. I was really excited when i saw it.
I’ve seen these modules in the parts express catalog. Always found the prospect a little daunting. This video will certainly help the novice sort out what he needs to get started. While I have some amps I’m very happy with (NuForce Ref 9SEs), I’m tempted to build one of these as a back up. Nice job, buds!
Thangs AJ. I'm glad to hear that.
Have you tested and compare it to a $3000 amp?
If yes than i would like to build it
The problem is he never specifies which 3k amp he is comparing it to. It's dubious and click baity as are his other vids. Not saying it's not a good final product, but not apples to apples.
There are a ton of amplifiers, that I would never be able to name them all. Some of them include the Rotel RB-1091 which uses just 1 500asp board (mono). When you build a 2 channel you can do it for much cheaper. There is also this article which entails what many manufacturers do (all using the 1000asp) www.audioholics.com/audio-amplifier/clone-amplifiers
123Toid Pretty hushed now? Lol Great vid . Awesome work . “Apples to apples “. 🙄🤐
A very interesting build. Despite all the naysayers, it's a fascinating project. A companion preamp would be a welcome 2nd step.
I would appreciate it if you could repair:
link to the 'zoomed out picture of the internals'. It is broken.
Thanks for all the work putting this together.
Should I opt for the 500 or 1000 watt system, will I need a bigger case?
What about a 2.1 system?
Great video, except the tad clickbaity title. I can only think of a couple of examples of big brand amps that use a simple single board class-D with an SMPS. Most of the amps out there in that price range have discrete class AB design with complex linear power supplies with torroidal transformers, not to mention the biggest IP expense with these brands is the preamp stage, which this amp doesn't have. Not trying to bash this particular project, but after weeks of research of attempting a similar project I came to the realization its not as simple as it looks to just make a class leading amp or integrated amp with 3 boards. Keep up the good work though, it would be awesome if can get your hands on boards from Hypex ( Rogue audios's integrated uses it, but notice the massive preamp stage which is not as easy to build). Good luck!
What pre-built products would this build be comparable to?
@@saltrocklamp199 Potentially a NAD M22 is the only that comes to mind, which essentially uses Hypex Class D modules and is essentially two monoblocks
Modern properly designed class D amps rape AB amps.
There is this myth out there that Class D amps are still inferior.
NAD does not even use AB anymore.
They went full on Class D.
As long as they are designed properly and quality parts are used Class D sounds just as good but wastes a LOT less energy.
Indeed, Hypex Ncore class D amps have over 100x times less distortions in highs(@6.6kHz) vs others class D on the market. ICE distortion performance is awful in highs, THD=0.2%! Any class AB amp in any price category easy kill such marginal class D as ICE is )) BTW, ICE frequency response is far not flat in 20000Hz and depends on a particular speaker impedance, all class AB or Hipex class D have no such problem at all! IMO, ICE 10x times overpriced and should be $30 instead of $300 ))
@@saltrocklamp199 Mostly sub 500 dollar range products. Klipsch powergate is comparable for 200.
It might be also worth looking at ICEpower 50ASX2SE 2x50W amp - also available at part-express for ~120$ --- almost plug&play and it can deliver ~25W for 8 ohms (enough for bookshelf speakers). By the way do you know where can I buy ICEpower boards in Europe ?
So are you saying the ICEpower amp boards from PE will yield sound performance/quality on par with Rotel or Marantz? I cant tell you how long Ive been wanting to do a project like this! Id like to build a unit with VU meters though.
Should I unplug it to stop the smoke?
Hey y'all, I just completed my build. Mine was slightly different in that I built two separate monoblock using the 200asc. The wiring was extremely simple and the sound is absolutely amazing when paired with the schiit Loki equalizer.
It is my opinion that a really good preamp would make all the difference in this setup and that is something that I'm looking into. If anyone has any suggestions for a fully balanced preamp please let me know. Once again thank you 123toid for this video.
I'm thinking about doing a build video as well.
Which pre u settled.?
Topping pre90
I’m looking at the Schiit Freya+
Thanks!
You're welcome
I'm one of those (super) snobby audiophiles (tubes, mono blocks, vinyl, TAS) who's been at it for twenty+ years and knows his music without using head cans. This dude's video just blew me away today!!! No link was listed for the XLR to RCA cables.
Thank you Vinnie. I am sorry about the link. I will update it now. For now, here it is for you: amzn.to/2Xdpqgv
@@Toid Danke
Great video, I would suggest a pan out on the video near the end to really show everything summarized. I was looking for the power supply connected internally and how everything came together overall. Great explanation of all the connections. 👍
That is a great point. I actually meant to put a picture at the end of the video and forgot. I added a zoomed out picture here: www.123toid.com/2019/02/how-to-build-hifi-amplifier.html
@@Toid the link is broken any chance you can post it again? Thanks!
Thanx alot !!!!!!
Thank you for this. I'm seriously considering this project. One question, if you replaced the US power cord with an Australian power cord, would that work, or would that burn it out as we run 230v 50Hz connections?
Don’t use such a shallow depth of field on your camera, it makes the close-ups difficult to watch.
Good call. I actually thought about that after I created the video. next time, I'll switch to a different lens. Appreciate the feedback
@@Toid You are shooting bordering macro. (high level of magnification) The only remedy will be smaller aperture and more light, using higher sensitivity (iso). You might try smaller sensor, but even smartphones struggle at this high magnification, at least at f1.6-1.8 and the bigger sensor size as of late. There is no aperture adjustment for smartphones. Wider angle might help a bit, but typically offers other challenges, as light and shadow effect, due to the working distance. Also, PDAF do not work that great at smaller apertures. You did a great job on the audio, kept the camera stable at high magnification, the exposure and lighting is just fine. The message of the wires got across, if people wanted to get the message.
This is great thank you so much Seth Rogan!
Lmao🤣
Message: Hi. I built the $3000 amp for $300 and it sounds great. Thank you. Was is the function of the ICEpower 6277849 Auto On/Off Wiring Harness for 200ASC? Is it for the LED on the button or does it power on the unit when the preamp is turned on? If it’s the latter it isn’t working for me. What might I be doing wrong? Thanks again.
what kind of input do these want to see? trying to design a guitar amplifier for a digital modeler- are there any modules with built in dsp these days for variable crossovers?
I built an 833A single ended triode amplifier at a fraction of a percent of the cost of the WAVAC $350,000 833A pair of monoblocks. It took many experiments to get it right but the sound is excelsior.
Thank you for taking your time and posting this video. That was nice of you. Sorry that the world has become inundated with people that criticize from a vantage point of anonymity. Lastly, there are $3k amps out there with very similar architecture to the one you showed us how to make for about $300.
Have a great day and for everyone else, it’s time to start showing each other a little respect. I never thought I’d see the world filled with so much hate. People need to mature a little more. We are obviously not parenting very well!
Sooo true . Great job young lad
