Tube Amp Archive

it is a blue cloth on it, sort of fuzzy. the output is extremely low on it. there is some oxidation I found on the power supply board that I cleaned off and just starting to look through the amp. Any help would be greatly appreciated. Thanks https://medias.audiofanzine.com/images/normal/polytone-min...

I'd be interested in this Schematic. I have one on my bench now and the ones I have found online half of the schematic you can not read. Any help would be greatly appreciated
