I have owned V4s and VT22s but never and older Ampeg. I recently bought a Gemini II off CL and met the gent halfway. He assured me everything worked and that it just had been worked on. Well, you hear the speaker hum but that is about it. I opened it up and sure enough it has been worked on. All new caps cobbed into the power supply etc. I fiddle with amps a bit and have a scope and generator etc. My main problem at this moment is I can only find 2 schematics. One shows 6L6 output tubes and the other shows 7591s. This amp has the 6L6s in it. It has an old sticker in it showing the tube complement as 6L6, the sticker reads Linden N.J. The coupling caps shown for the 6L6 are .1 mf but it has the .02mf caps in it for the 7591s? I am not sure what is going on here. One shows a full wave rectifier and one shows a half wave rectifier? The amp is missing the voltages for the plates etc in the preamp section, I am wondering which schematic to work off of.
Any help would be greatly appreciated.
