Hello Everyone,
Hope this is the right board.
Wanted to share a Champ Reverb build I did more than 12 years ago. Took advantage that I have it on the bench for a loose joint around the input jack to take and share some pictures.
The finished result sounds outstanding. Very much a rock amplifier, from low/mild to high distortion. Not for clean jazz.
The starting point was an SS bass amp that I bought at a thrift store for $5.00 USD, and the following layout:

I took a Champ AA764 layout/schematic, and added the following:
* A treble boost
* A mid adjustment in the tone stack
* Inserted a Deluxe Reverb's reverb into the circuit.
Can't remember but believe it was a AB763.
Attached are some pics and the only notes that I found which includes my board layout, aa764 note, reverb notes, and some additional pics.
Hope everyone has a great weekend!
