I just got this amp and it's high on treble ang low on volume. If the "loudness" pot is turned completely off, you still get the reverb volume by turning up the reverb pot. There is virtually no base and the volume with both the reverb and loudness pots at 10 is like a Princeton reverb on 3.
Yes I know its either wired wrong of I have a few pesky caps to deal with. But, I don't have the schematic and I've only been doing this tube amp salvage thing for less than a year. I've only worked on Fenders and these tubes, 6EU7, 12AU7, and 6BQ5, are foreign to me.
If anyone could be of assistance in getting me going, I'd really appreciate it.

The schematic is in the Pitman Tube Amp book I think.
