You might try Davidson Amp Repair. The guy's a little on the odd side, but he does good work. He put a new power supply in my old Ampeg SVT before I sold it to Ben. Six months have passed and it seems to work better than ever. Don't know how to contact him, but he usually has ads on the back page and want ads of the Scene.
You know you have problems, with both money and alcohol, when you find yourself shoving beers down your pants outside a Features show.
