I have heard about old PA Amps, Tape Recorders, and Film Projector amps being used for guitar amps. Some with mods and some without. What are you guys using? I recently got a Wollensak tape recorder and it sounds pretty darn good in its stock form. It is about 10 watts. I paid $25 for mine. Here is a video clip from another member here. I have an At Mars amp which uses a Bell & Howell Filmosound 179 movie projector as a starting point. It is modded pretty heavily but uses the original transformers and some other parts. I also have had a Bogen PA amp converted to a Fender Harvard for a long time and it is amazing. Sorry no clips of this one.
