You're never going to find a replacement can with more than 4 20uf sections (don't really know how Ampeg wired these originally), so there will be a couple extra 20uf caps sort of shoved off to the side once the recap is done. Different techs seems to find different ways of attaching them to something solid. But anyway, this is normal.
I believe that is what appears on the schematic on the inside of the back panel. The cap can that is actually in the amp corresponds to the later B circuit. My tech will see what caps are actually in it when he removes it. I am assuming this is version 1, but I see on the Fliptops site that they sell cap kits for two versions, 1 & 2, both with 6V6 power tubes. It uses 6sn7 preamp tubes (6sl7 for trem and PI with a 5Y3 rectifier.
I'm hoping that this one will break up a bit when cranked up; unlike my M-12 which stays clean all the way up. So far I'm very impressed by its warmth as a quiet jazz amp.
