When I first got into electronics about a year ago one of the first things I tried was replacing caps on a cheap Chinese amp I had. I opened it up and figured I would start with these 2 blue ones right here. I learned that they were film capacitors and they were 1 uF. So I ordered so 1 uF film caps and I got the WIMA because I thought they looked cool. Well after "soldering" those caps in I plugged it in and it sounded like SHIT. I thought I screwed something up bad. Then I noticed it was getting better, then better and better and after 5 hours or so they sounded fantastic. So when you said "I'm going to let this BURN IN" I wanted to reach through the TV and hug you. I count to countless people that say caps don't change and this and that. You have good ears my friend. One of my favorite things is to listen to film caps change. I never learn and I always adjust things before they settle down.
I plan to let it "burn in" for at least a week playing 8-10 hours a day before I make any judgements or consider any changes. It will be interesting to see if the scope pattern looks different as well! It sounds better and better the longer it has run!
When you make these beautifully wired amps using the 300b set up. After all your expert knowledge and testing and diagnosing the circuits. I would love to hear the amps run different types of music I understand videos can get long then also the copyright of music maybe an issue. I so much want to find a 300b SE amp yet I wish to hear them first. Love your work an explanation of the separate stages throughout your builds.
All you are going to hear is your computer speakers. I'm sure there are plenty of You Tube videos of people playing 300B amps, but you aren't going to hear a 300B amp on your computer.
@@SkunkieDesignsElectronics 13:44 my computer runs through my tube pre amp to my tube amp to my Altec Lansing three way speakersI have a DAC board in my computer but ok I can get it.
Great job keep it up ! I just bought the Beast of a tube integrated amp 59 pound Doge 10 MK2-B Geez its powerful also just bought the Freya Plus tube preamp that's fully balanced
22.8 watts of plate dissipation 380 HT 0.060 amp current cathode max anode dissipation is 40 watts will sound good this amp 380 HT x 0.060 cathode current = 22.8 watts
Can I ask, with testing the voltages, is that to ensure components are all working correctly or possible errors in the wiring as a safety precaution? 🤔 I'd imagine it's a bit of both, but have you ever seen really out of spec to expected before and what was the culprit?
I would say for me testing a new design, I'm looking to ensure my calculations were correct and I am seeing what I expect to see. It also rules out wiring mistakes and especially measuring the voltage across the output tube + cathode voltage lets me know how much bias the tube is running at.
@@boris1970able Yeah, just getting this started up. Not sure if I plan to make kits or finished products yet. I'm leaning towards kits with prefabricated chassis.
So all said and done how much does something like that cost? Look how close the voltages are on each channel, that's going to be a good sounding son of a bitch isn't it.
With all new parts and tubes, around $900. I already had the transformers and chokes from a previous project, which was about 1/2 the cost. Most 300B tube builds I have seen online spent that much or more on just the transformers!
@@SkunkieDesignsElectronics Thats not bad then knowing the perspective. I looked and the transformers have a 10 week wait time, they must have a lot business.
@@nickk6109 There isn't a shortage there WAS a demand. The idiot that's in office now put an end to the pipeline and that is what was causing high demand, but we weren't actually short on copper because it was never used. It's just people trying to time the market and that drove up the price. It's there, just more expensive it will go back down.

@@SkunkieDesignsElectronics That's exciting!! Hey, POLYSTYRENE!!!!!!!! hahaha
This is some neat wiring on a point to point project. Wow.

High quality and safe build practices. Thank you!
You're welcome!
Amazing square wave
Great job keep it up ! I just bought the Beast of a tube integrated amp 59 pound Doge 10 MK2-B Geez its powerful also just bought the Freya Plus tube preamp that's fully balanced
Sounds fun and I love their name :)
good gen got the same one need to cover the cathode resistor ends
Beautiful looking amp. Like it😂
Please post a video and show a video how it sounds like just a simple sound clip would be neat :)
czcams.com/video/u2fOsMdt7Ps/video.html LOL :)
Have you ever tried any .1 uF polystyrene film caps in series with the bypass caps? The sound of polystyrene blew my mind.
Do you really mean in series?
👍👍

groovy
Great looking amp, which record gets played on it first?

Hi! Great amp build. Looks like you didn't get the cathode bias meter in. Are you still planning to put it in?
Yeah, I got it put in as a "final touch" between the 6SN7 tubes and the choke.
pls explain sound diff to 211 type tubes
I haven't played with 211 tubes yet!
What is the use of the potentiometer connected to the heater pins and the cathode resistor , and how is it used?
Thanks
It sets the balance point for the least amount of noise.
Thanks, what is the position you set it too before you start up?
🙋👍❤️
any audio test?

Its not audio test we d like to listen to the sound ...
Are you selling your amps ?? I’d be interested in one
I'm not currently ready to sell any, but I plan to try to do some limited production in the future!
Well you are doing advertising under a company name so might as well start making money 👍
@@boris1970able Yeah, just getting this started up. Not sure if I plan to make kits or finished products yet. I'm leaning towards kits with prefabricated chassis.
@@SkunkieDesignsElectronics finished product would sell easily, kits not so much 😉
Sell kits with the option of an additional assembly charge

@@ranbymonkeys2384 There's also the global shortages of copper that are impacting lead times for delivery.
