Hope someone finds this useful. It was glued to the inside of the chassis and I have not seen it online anywhere else.

A bigger image would probably be more readable.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Ha, needed another zero in my resize attempt. Should be better now.

Thanks!

Ha, I laughed at that too.

Also in Newcomb land...tone controls, when fully clockwise are minimum. Strange place but nice sounding.
