1200s tremolo probs
« on: November 18, 2000, 07:36:00 am »
I have Sunn 1200s. Tremolo doesn't work any more. Apparently part of that circuit is in a circuit board. Iv'e tried to troubleshoot with no luck. I have tried to locate some of the transistors on the board to replace those and I'm not having any luck. Any suggestions?, can the board be found anywhere?
