- In Part 1 of this video series, we will begin to construct, from scratch, an amplifier and provide a new speaker for an empty 1954 Supro Supreme amplifier cabinet, sent to us by a viewer. All steps of the process are explained and demonstrated, from repair of the cabinet, design of the amp circuit and chassis, selection of components to purchase, construction of a sheet metal brake to form the chassis, and machining of the chassis for all components. In addition, we will take a break and go for a ride in a 1932 Ford Roadster.

We all Love you Uncle Doug. You are a shining ray of sanity in an often gloomy world.
That's nice to hear, CR. Things have definitely gotten a lot gloomier just recently.
Wait!, our Uncle is SANE?! Awwww, that's no fun!
Politics, riots, and sheer lunacy may bloom like a weed but Uncle Doug is always Uncle Doug.😁
Like death and taxes, we're here for the duration, Randy :)@@Slugg-O
Hi Doug, I have watched your channel for years. There's no one on the planet that could hold a candle to your skill of building amps and drawing schematics and explaining everything and your outrageous talent of building hot rod cars like the plastic models I used to build and paint as a kid by Mattel. There's no one on CZcams that is as entertaining as you are. I find you to be a diamond in the rough. You just don't find older guys in my age bracket quite like you. I think the world is lucky to have someone like you doing these videos and hope you go on doing the things that you do forever. Brings me back to a time when I was a kid and loved guitars amps and hot rod cars and surf music, but like my sister once said to me, you can never go back home .You have a way of mesmerizing people with the way you speak and your vast knowledge of everything. People have no idea of your genius. All I can finish with, is saying thanks for the years of videos. Michel Newell from Niagara Falls, Ontario Canada
Wow.....Thanks so much for the very kind and wonderful comments, Michel. Viewers like you make our work quite rewarding :)
I so appreciate the “take the training wheels off” direction- I fully believe that you need the schematic to understand the circuit, and make component choices from there. Building and troubleshooting are so much easier when you know what you are (supposed to be) looking at…
Thanks Uncle Doug!
Glad to hear it, Jay. As a child, I begged for my parents to leave the training wheels on my bike.....but after a few minor crashes, I appreciated their "tough love" ;)
Mr. Douglas...your dry sense of humor is cracking me up...much better than most standup comedians these days...and then I stay for the electronic education...what could be better?!?!?! :-). (Gotta build me one of those speaker-wire handles! Sweeeeeeet!)
Thanks, Edward. We sold the original speaker wire handle on Ebay for $950.......minus fees, we cleared $1.62.
A scratch built vintage amp episode is a brilliant idea! It breaks the tried-and-true repair aspect of your channel into a new facet to this diamond called Uncle Doug. I am looking forward to the promised sequel to this exciting endeavor. Well done.
Glad you enjoyed it, Alex. All credit goes to the viewer who talked me into it :)
I does not matter what other people think, If you like to have the hood on when you are driving, have the hood on. Are you driving and owning it for YOU or for other people..... Listen to what you like to do, not what others like you to do.
Thanks for the pep talk, G. The question was largely rhetorical.....the sides stay on :)
It’s a bully world. Lol
@@benlogan430 Yes, it is, Ben :)
Jeezus uncle doug, that home made press break is why we love your work. Fabulous as always.
Thanks so much, Rocket. I wish I'd made it long ago :)
The mike doesn't do your ford justice Doug, It's good when one has to their brain for a project. Excellent video mate! Nearly forgot, sides on.
Thanks so much, Antony. I agree :)
As a 14 year old here in England back in the sixties , I looked in awe at these kind of hot rods ,back then there was only one car in our road , and four motorbikes , however , even then I can remember a Chevy Bel air coming down the hill towards me , it looked like something from another planet and the sound of a V8 was very special.
Automobiles are such a strong part of our culture, Graham. I've been a car nut for well over 60 years :)
Agreed. I saw a Bel Air way back when I was about 18. Also a Camaro that won a rally. Fell in love with these big V8s. Had company cars so had to drive four or six cylinder cars most of my life. Now I have an F Pace SVR. Love that V8 burble on idle, and the power is awesome, but inside the car you don't get that classic V8 sound that I love so much.
England has a proud history of sporty, quality automobiles, but none of them seem to offer the "V8 sound" you enjoy, Eric. I guess you'll have to find it vicariously through American vintage autos :)@@ericrawson2909
Another amazing video Doug! I'll never be able to thank you enough for how educational and inspiring these videos are :)
Glad you enjoyed it, Milo :)
The car looks so ,uch better WITH the hood sides. It is beautiful either way though of course!
I agree, Mike. That's the way the car has been ever since the video was posted. Thanks !!
beautiful hotrod, I've been a car guy since the middle '60s and have been around and involved with 'rods all my life. it's great to find another person who enjoys amps, music and cars....I almost forgot he cats.
It sounds like we are kindred spirits, Gerald. Thanks for your input.
Delightful build Doug, thanks for sharing!
You're welcome, Kley. Glad you enjoyed it :)
There's something always so rewarding about starting with a pile of parts, making a "thing" and seeing it come to life. Doesn't matter if it's a car, an amp, or really anything that you've built with your hands and mind.
I agree completely, DK. You spend years developing skills and a project like this is a great way to exercise them :)
Hood side on...absolutely beautiful...you are one talented fella uncle...
Thanks, Glenn :)
Looking forward to this Uncle Doug Classic Series.
I hope it lives up to expectations, H1 :)
Home made press brake….. nicely done old man…..
Thanks, TM :)
Uncle Doug posted a video today. Today is a good day.
I hope so, AJS :)
Uncie Doug!!! Us Mutsy a new kitty. I remember Jack but not Mitsy. Of course my imagination is way better than my memory!
Same here, CC.
Your my favourite Uncle, thanks Doug
Thanks so much, CL. See you at the next family reunion :)
Nice job on your "Pat. Pending" sheet metal brake. Interesting enough I went to school with Pat Pending and his brother Bill the founder of the Billy Beer company. That was at Chris P Bacon Elementary School in Arkansas. I wasn't aware he moved to West Texas.
Seriously though.....well done video and great concept for a series. Can't wait to see how it turns out.
Thanks so much, Reggie. Regards to the Tang sisters, Wu and Poon, if you happen to see them on the street :)
I agree 100%, if you can’t figure it out yourself or learn to figure it out, your not going to get far doing this.
Exactly, ILC :)
That really is a fantastic bending brake you built Uncle. I'm stuck with the crappy one from Harbor Freight. I modded a
large wood base for it. Clamped down on a large table you get better control while bending the average thicknesses
sheet metal one uses for chassis. Was indeed interesting seeing you make a chassis and the electronics layout design
from scratch. Thanks for the ride Uncle!
Thanks for your nice comments and input, HM.
That National Amp I have... 1952..same circuit with 3 - 47k inputs, 6j7, 6sc7 preamp. I had to rebuild most of it as it had been stored in a high humidity. Wish I could post a couple pictures. Nice work as usual!
Thanks, TM :)
Hood side on. Cool build
Thanks, O :)
That Supro badge is slick! Building an amp can definitely be expensive but when you see a modern hand wired 57 Custom Champ for $1200,it takes some of the sting out of the cost of a home built amp. I have a lot of great amps (and some not so great,lol)that I wouldn’t be able to afford if I just bought them from a store. Plus it’s a lot more satisfying to build them. Can’t wait till the next episode.This is gonna be a cool amp!
Thanks for your very nice comments, William :)
@@williambock1821. Yeah, & when you're building it yourself you can spread out the shell shock to the wallet by buying the parts stage by stage, & perhaps hide the cost from the missus more easily.
Like my hifi amp & speakers I've built, which cost me about $5.5k, but spread out over 2 years, we're more like a dull ache, than a severe sting!
Spread out the misery......makes sense to me :)@@nevillegoddard4966
it's a good day when there's a new uncle doug
I hope so, Z :)
Nice ride! Looking forward to the build!
Thanks, Fred. All three videos have been posted.
Ah Man.... Your going to make us wait to see where the OT is mounting!
😧. I'ma wait'en
Thanks U.D. Love your videos and all your hard work.
It's always worth the wait.
Thanks !! I hope it's worth it, Mark ;)
Woohoo! Yer back, Uncle Doug!
Yes, indeed :)
Excellent video. Also I think the Roadster looks best with the hood sides installed. Thanks for your vids.
Thanks, Pete. I agree :)
I'm excited to follow this project. I'd suggest using a eyelet board. It's easier to position the components. A lot of viewers might benefit seeing one laid out and installed. Looking forward to part two.
Greetings, Ray. I'm a dedicated believer in point-to-point wiring using terminal strips.....it's just my style :)
@UncleDoug I like point to point wiring too. I wasn't sure if you'd done a build with an eyelet board. But I understand it's better to stick with what you like.
I think eyelet boards are wonderful for mass production, where the boards can be pre-assembled in quantity, but for one-off builds, I consider them to be an unnecessary complication. @@rayvoorhies7180
Makes me wish Radio Shack was still in business.
Me too, RB. I miss the convenience.
Gidday Uncle Doug! 62 & my oldtimers disease must be trying it on! Sorry mate; I'd completely forgotten I'd already seen this part of the series, AND that I'd commented & liked it, AND that you'd kindly replied! D'oh!
Nevertheless, I must have been so impressed & really, blown away by that beautiful '32 Ford that I forgot to say anything about the 'suprinceton'.
I guess, like the '32, I just love brand new & reworked stuff going into old 'externals', helping them live to please another generation! Great fun!
And before I forget, give Mitzy & Jack a headscratch for me would ya! I love them both! Unfortunately, I don't think I can have any more kitty cats - the poor buggers keep dying early on me!
Great idea using dowels to plug the 12" speaker bolt holes! Nearly flamin invisible! I like how you installed the new handle; I'm gunna get meself some o that gun blue stuff! It seems to magically age brand new steel. Does it chemically bond with the steel? - & does it prevent corrosion too?
It would be nice to see a complete modified circuit of your Suprinceton once you've finalised it. A little tricky to combine the 2 circuits together in my stoopid brain, & you draw them so well.
Please tell me what a 'reverse audio taper pot' is? Is it, kinda 'antilogarithic'? And how would the tremolo pot respond to say, a log pot instead, for example?
Yeah, so we all know we can't solder to aluminium right? Well, wrong. You can! I just watched Mr. 'Hackaday' do it! The trick is to plate the aluminium with copper first!
All you need is some copper sulphate, some ferric chloride & table salt! Not too difficult, & I watched him use his resin-cored solder to perfectly tin an aluminium can & solder a resistor & an led to it.
As bright & as shiny a solder joint as you'd see if it had been a copper can! Just miraculous! Impressive & unexpected to see a pink copper patch so well bonded to aluminium! No flames required. Especially easy when you're building an aluminium chassis from scratch!
Of course, your new Suprinceton chassis would be all done & dusted by now, but maybe you could think about that for your next ali chassis.
It was exciting to see all the new bits layed out there for the amp - like unpacking an amp kit! I bet it was fun for you too!
What's up with that bender you made? You're gonna have folks & blokes wanting you to build them one of those too! It's a bloody beauty! I chuckled at the cussin & ICU comment ya funny bugger! Lol!
Have I got it wrong or did you score yourself a real nice chassis hole punch set from a yard sale a while back? Or maybe it was Brad?
Nevermind, the 'toob' layout looks nice mate, except I probly would have put the jacks in front of the 12AX7's to stop klutzes from damaging them & burning their unco little soft fingies.
Tell me more about your legendary 'D' shaped drill bit! Where would I find out more about that?
You nearly had me thinking you'd completely forgotten about the output transformer, but no, of course you hadn't! It's gunna be interesting to see where the sub-chassis for it will go though. I suspect there's not much room left inside the box.
Last time I commented on the '32 Ford I likened it a formula one open-wheeler! Then I was thinking how much fun it would have been if it had a stick shift instead. But of course, the F1 cars now are even 7 speed autos!
AND they have auto brake flaps on their rear wings now as they approach the corners. So you've got yourself a virtual 1932 formula one racecar there mate! Yeehah!
Greetings, Neville. Wow.....lots of questions. Gun Blue oxidizes the surface of the steel, protecting it from further oxidation. A link to the final schematic is included in the video description. You'll have to do an internet search for Reverse Log pots to get a proper explanation. Thanks for the soldering-to-aluminum tip.....I'll check it out. I did get a hole-punch set a couple years ago. I'll keep your suggestion on output jack positioning in mind for future builds. Merry Christmas !!
Graffiti yellow and chrome hot rod. Jeff Beck would be proud...
I hope so, Luiz. I miss him :)
the car sounds luscious, amazing
Glad you like it, MC :)
Loved the way you handled the parts list and layout requests 😂
Sometimes "tough love" is the best approach, Rich :)
Without the sides! Nice and informative video, as always. Your yellow car reminds me the late Jeff Beck's. He had a very similar car like that, but I don't know where in England he could enjoy it. Their roads are very narrow. I'm not sure but I think most of his cars were left sided wheel! He was a very american englishman! Stay healthy and God bless you!
Thanks so much, Marc. Will do. Likewise :)
Another fantastic video, and a timely, dare I say "uncle-ish" encouragement. Well done nudging people to step outside their comfort zones and develop their own BOMs!
...and then you highlighted the lesson by expressing your own misgivings about using the brake for the first time on a machined piece of metal. Ultimately you put on your big boy pants, trusted the tool, and ended up with a success.
That is the best sort of mentorship.
Also, the lope of a big cam is a thing of beauty. .
Thanks for all the great comments, NN :)
Makes me happy to know there are still rocket scientist among us creating the sheet metal bending tool puting your mind to work.
If you don't use it.....you lose it, Lane :)
Awesome video Uncle Doug. I swear you passed me on Kessel Run in that hot rod doing about .5 past light speed.
Was that you? I thought a tortoise had escaped from the zoo ;) (JK)
AAAAAArgh! Can't. Wait. For. Next. Video!!!! Going to have to rewatch some just to quell the shakes..............
As for the side panels, on is less drag, off is more showy. Do you prefer a nice dinner dress or lingerie? Depends on the situation I guess.........
Thanks for the analysis and excitement over the video, Nick. If it helps, the wiring is finished and the little jewel is working perfectly !!@@NickCoplowe
@@UncleDoug it helps, and also it doesn't!
It is a remarkable great looking rod that you have there uncle Doug. The hood sides should stay on. Great video.
Thanks twice, PBM. On it is.
Olson Electronics was a chain of stores similar to Radio Shack in the Midwest... Milwaukee in my case. They carried a much more complete parts line than RS, and also sold clones of Knightkits under the Olson name. They also kept young gun bands (like us) supplied in mic stands (Atlas clones), microphones (Turner clones), and as you discovered, musical instrument speakers which were better than Radio Shack offered, but more affordable than Jensen or CTI.
Thanks for the interesting info, B :)
I'm in the Cleveland area... Olson operated before my time, but I've had some of their products through the shop.
Whoa! That supreme schematic is EXACTLY the same as the amp in the Filmosound model 179! (I just converted one last week, leaning HEAVILY on the knowledge I’ve gleaned from your videos I might add!)
Thanks for sharing, Andy. We're glad the videos have been helpful.
Nice cliff hanger there with the output transformer final location. I swear these videos could be 3 hours long and I would still be wishing they were longer!
Glad you enjoyed it, D. The solution is somewhat unique ;)
Beautiful '32 Uncle Doug! Looks great sides-on or sides-off. Matching yellow backlit instruments lol nice! You're a braver man than me though UD with NO MUDGUARDS! Like a formula one driver!
I'm betting the little UD Valco/Princeton bespoke hybrid is gonna sound sweet as a honeypot & can't wait for the next edition! Thanks for a great video! 😃👍
You're welcome, Neville. Thanks so much :)
A very cool video! I'm gonna hold my breath until I hear where the output transformer goes.
Thanks, H6. Prepare to be astounded ;)
you are the best....... glad your all well and thank you again!
Thank you, too, Paul.
Great show Unk Doug. Sides on like you said, looks sleeker.
Thanks, TD. I agree :)
It’s a good day when Uncle Doug posts a new video, looking forward to it.
I hope you enjoy it, Steven :)
Excellent work, that is a beutifull machine!
Thanks, Charl.
I agree, hood sides on. Let the intrigue work in their minds of whats under the hood.
I agree. Intrigue it is :)
I'm big into cars but this one it pretty! The amp is what I'm here for but I completely enjoyed that!
and hood side on!
"not big into cars"....I was a bit thumb fingered! :-)
Thanks so much, John :)
Definitely, hood side on, Uncle.
So be it, Maurice :)
great stuff. thanks for the hotrod clip shes a beaut
Glad you enjoyed it, SS.
Hood sides on! My Uncle has a 1929 Model A business coup. He is 85 so he can't drive and I am the only one who drives it anymore. It is 100% stock in every way besides as bit of cosmetic work. Hard to drive, bumpy, rattletrap, but fun.
Thanks for sharing, SHW :)
Myself as a player And a mechanic understand the mechanics behind creation same as the mechanics behind the playing.❤
Indeed, Charles. Thanks for sharing.
You Rock Uncle Doug
Thanks, S :)
The amp build is in my opinion among your very best ever produced and the 32 is an absolute work of art. The side panels are a must with louvers defining the attention to detail throughout l the perfect hotrod, great job Uncle Doug
Thanks so much for your very kind and positive comments, Mark.
Another day, another cat! 😂 cheers! (UD, it's Luthier Vandross btw). Hope alls well brother!
It is indeed, Luthier. Thanks !!
Thanks a lot doug really enjoyed the video and the humour. Take care till the next installment.
You too, Mix.
Right up my Alley! Great Content.
Glad to hear it, LW :)
In high school, my pop was a real demon on that vintage Ford coupe. He was a machinist, even in high school, and he hot rodded the dog piss out of the Flathead Ford engines of his day I think late ‘40s or very early ‘50s. Then Korea was calling. He never went back to hot rodding cars afterward; at least for himself, but he sure reminisced about his prized hot rod Fords. I myself was nearly born in his ‘49 Mercury, which he also thought highly of. Crossing the San Mateo bridge was dicey to say the least. He bellowed strict orders that my mom was expressly forbidden to give birth on that bridge. What sounds humorous is deceptive. He was never more serious. That was the DI, and he gave an order. It BETTER be obeyed.
What great stories, John. Thanks for sharing :)
Sweet. A new uncle Doug vid!!
Yes, indeed, David :)
Aluminum is soft enough that you can safely use a wood cutting blade to cut it. I’ve been doing it for years without any problems. Another option for removing the handle pins is to center punch a dimple then drill down through the double heads that trap the bracket and push it down out of the cabinet.
Both are good suggestions, Tom. Thanks :)
I bet in a prior life you were a master builder for the Egyptian Pyramids! What a talent you have among many!
Wow....Thanks so much, Gerald.
"Part One of a Series" Oh my oh my!
.....and Part 2 is currently in production :)
Good to see you again Doug.
I always look forward to your videos and restorations
Thanks, 74 :)
woooo hooo a new Uncle Doug vid!!!!!!🕺🏼😃
I hope you enjoy it, Ben :)
Great stuff, Doug!
I just made a zero-budget current-limiter by splicing one extension cord in series with another. Then you plug a regular desk lamp into the one in series. LOL! Works! (No way to switch out the bulb though, so you have to unplug and replug the D.U.T. But the switch on the lamp at least cuts the power. This is what the kids would call "ghetto".)
Have a buddy who does house wiring who's been telling me "I have all that stuff" for 2+ years now. Finally got sick of waiting for him to help. On with the Korg Mono/Poly repair! (Already have a Variac and Isolation Transformer, this was the missing link!)
Glad to hear of the rather rustic addition to the diagnostic arsenal, AQ. I hope it serves you well :)
@@UncleDougIt did! I brought the Korg Mono/Poly up slowly and was satisfied there were no major faults. Had already replaced the busted pot with a temporary piece of junk from some computer speakers (you can see it dangling out of the hole), so I then put it straight on the mains and lo and behold...
czcams.com/video/wG5E9vczoBk/video.html
Frankly I was a bit disappointed it was such a simple repair. But I'll take it! Taking an ain't-broke-don't-fix-it approach on everything else, including the filter caps. It all seems fine and zero hum. Amazing after 35 years in the bottom of my old music buddy's mom's closet. (That's what dented the front panel and busted the pot.) I intend to put it up on the market so "mostly unmolested" will be a selling point.
Indeed it will, AQ. Thanks for sharing :)@@AdmiralQuality
I love the hot rod. I can't get enough of it . Reminds me of my youth going to my grandfather's junk yard in the 1970's and him fixing cars and pulling parts. Thanks for the video Uncle Doug!! Awesome!!
Soo glad you enjoyed it, Marcus :)
Thanks for the ride. Unexpectedly pleasurable.
Glad you enjoyed it, C :)
Very much enjoy the amp repair , building , and the hot rods. As i've said before you are a very punny and entertaining feller. I could stand to see your 2 wheeled gems from time to time as well.... Thanks for being here Uncle Doug !
That's great to hear, RD. Thanks !!
Uncle Doug, thank you for yet another highly educational and inspiring video. Amps, jukeboxes or cars, there seems to be no challenge you cannot overcome, and your attention to every detail in pursuit of the best possible outcome is second to none. The luck owner of this "Suprinceton" is going to get an amp that has been lovingly crafted!
Wow....Thanks so much for the very nice comments, Greg. We really appreciate them :)
Waiting on Sparta 2
How about Part 2, Brian, it should be even better ;) @@brianmichaud3668
I agree about the hood sides on, but can see that there are times where it can be fun to run without.
Thanks, RR. Fortunately, it only takes a couple minutes to remove them :)
cant wait to hear this amp!
my vote on the 32 Ford:
hood sides on.
Thanks, Rock. I agree :)
"Patented D-Shaped Bit" Hysterical ! 🤣
Actually patent pending ;)
I was watching another CZcams channel, "specializing" in tube amp repair/restoration, and I can not express how much better your work is relative to this other person. I didn't, but I wanted to tell him he needs to watch your channel to understand how to do this with perfection and precision.
Thanks so much for your kind appraisal, S-L.
Another great video Uncle Doug. Aluminium soldering is quite easy. You just need the right type of flux. The flux I use came with a MAP gas torch, and worked fine with standard iron and solder . I have found this useful for soldering to aluminium tape for guitar cavity shielding.
Thanks for the tip, Terry :)
You are the man Uncle Doug. Everything you do is top notch. Thanks for always teaching and keeping things hilarious.
You're welcome, JMB. Thanks for the nice comments.
🤗 @ 1:01:30 chassis fits. Ride-along was cool breeze🍀✝️
Sometimes we just get lucky :) Glad you enjoyed both, J.
Hi Uncle Doug - I really enjoyed Part One, and am looking forward to Part Two. I recently added bias-wiggle Tremolo to my scratch-built 5E3 and was underwhelmed with the intensity. After a few mods, I finally got to an acceptable intensity (but I may go back and change the power stage to fixed bias). I'm very interested to see how you add tremolo to a cathode-biased power stage. Thanks for sharing this project.
Faced with the difficulties you described, I caved in and changed the circuit to fixed bias. Since this is a video series, I did not want to end up with hours of experimentation and uncertain results. My inclination was to apply the trem output to the cathode of the second triode......but that is also where the NFB connects.
you are the KING
Wow....thanks, Steve :)
We’re excited for this video as much as you doing it! Cant wait to do a full listen this evening after work.
We hope you enjoy it, RM :)
Thanks Doug for your very interesting, wonderfully detailed, and humorous 'SUPRINCETON' trilogy.
That Supro cabinet looks very much like my 1952 Valco OAHU 'Supreme' amp.
You're welcome, Tony. Since both Supro and Oahu were created by Valco, the cabinets may well be identical.
Great video uncle Doug!
Good job on the chassis fabrication, and the building of the brake.
As far as the hood sides on, or hood sides off, I would take the indecisive approach and leave one side on and the other side off. You will need to decide if, left side on, right side off, or the opposite. I can't figure out everything for you!
Thanks, Paul. Don't worry about the hood sides.....the decision was made long before the video.
Knowing there's going to be two or three more video's is the best part. With the hood sides is better.
Thanks, ILC :)
The solid lifters are acoustically glorious. Thank you.
Thanks, GG. Like a castanet solo ;)
When a craftsman needs a bending brake.. he simply makes one himself! ( same thing i did!) Good stuff!
Thanks, Gene.
Sides on the rod looks the best to our eyes! Thanks for the ride!
Thanks, Marty. I agree :)
Great start Doug
Thanks so much, X :)
Brilliant start to the latest amp, leaving no stone unturned. Appreciate the return to the Amp/Hot rod format to the videos
Glad you enjoyed it, Garry :)
Keep it simple is the best approach to the BOM when making a CZcams video. Thing about the tube deal is you might get it done and find the one of the transformers are not quite right. At first I was a little disappointed in no list. Not that I wanted to build this amp but see if I had an any donors that would work. Matching the outputs to the output transformer is a big part of the circuit design and there are many others that discuss this process. I’m totally with you on the “Build to your own plans”. Nice series.
Identification of the transformers is provided on the schematic posted in the Video Description of the Part 2 video.
I gave you a like, like I do on all of your videos. I give the likes on my phone, but I watch the videos on my big screen TV.
We always look more youthful on the big screen, Michael.....at least our hands ;)
Great to see another video from you! They're immensely helpful for those looking into amp building/repairs, because you take your time and explain everything so well. Thank you, Mr. Doug!
You're welcome. We're glad you enjoy the videos, Martin.
I have used the c12q speakers and I like them alot
Thanks for the input, Mark :)
I just scratch built a champ chassis with your 2x4 and hammer method....Harbor Freight breaks looking very good to me and we are getting a new one 2 miles from my swamp on the 23rd.....(-:
I agree, Pete, and built my own brake for chassis fabrication.
LOVE your videos! Thanks!
You're welcome, PS :)
Nice work, UD!!
Thanks, GL :)
