CarverFest 20w Tube Amp Schematics & Pictograms

Bob asked me to post the most updated schematics and pictograms for those that took home incomplete copies. If you are going to build your amps at home, please go by these diagrams!!!

If you click on the images they get a little bigger, if you need a larger image, I can email poster sized images.

Ah, are these the "final" version 121.2 or 123.7? O:)
In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence.

The best way to enjoy digital music reproduction is to never listen to a good analogue reproduction.

Thanks for sharing that!
I've been out of the loop for a bit, are any of the components used custom or hard to get?
Looks like a great winter project. \:D/

Re: CarverFest 20w Tube Amp Schematics & Pictograms

FYI, Bob had recommended not using the (2) 7.5 volt Zener diodes in the biasing network as his opinion of them is that they were of inferior quality. If you overheat them or in my case if they fail on thier own you will indeed experience the plates glowing red hot in the output tubes (6BQ5). He later suggested to me that he recommended a 17 volt 2 watt zener to replace them. I have not yet sourced a replacement diode. Harry

That winter project may become a year long project, we called the company that made the Transformers for Bob, and they told us that they were custom made for Bob to Bob's specs, we can't even get them without Bob's permission.

Re: CarverFest 20w Tube Amp Schematics & Pictograms

I have been reworking the Pictograms so that they are easier to follow, I went off of my Amp (because it works flawlessly) instead of the Pictogram that I got from Bob, so if there are differences, please give me a little time to cross check the two.
