I have an EP-2 from the 60's that I picked up in the 70's. It's got 3 small tubes. Never done anything to it except replace the tape once or twice (maybe a tube) and it adds quite a nice punch to whatever ya plug it into. I just keep all those rollers and stuff cleaned up. It is really quiet, however, the little motor makes a mechanical noise and I found that if I stand it up on it's side, it stops making the noise. It just seems so freakin fragile that it stays at home or studio. Good luck on your project. I think it's a piece worth having around. In fact I think I'll plug her up tonight just to fire up those caps.
