I have inherited two tube amps but there is no schematic diagram. It came with two sets of seven matched 6550 tubes (yes, seven). This is my first posting on the forum and I am not sure how to attach a picture.Any suggestions?
The Hammond transformers may be a clue. I believe in the early '50's Hammond made a brief foray into home audio essentially adopting their organ amps. Good luck in searching for info, but you might want to check out that possibility.
