Does anyone have a schematic they might e mail me for this PC-303 board. I've got a real weak tremolo circuit. Speed is functioning but you have to turn intensity full open to hear it. I took a quick run through with a ohms meter and there is no shorted caps or open transistors so I'm thinking a leaky cap or failing transistor. Any ideas or typical problems info is sure welcome. Thanks Steve C

Don't forget that the effect is really vibrato (pitch shift) and not tremolo (volume change), so it may seem weaker than you might think.

WOW Thanks, I didn't even note that when reading the schematic. Yea, that would be why I thought after recaping and changing out transistors it still wasn't right. Now that puts what I hear in perspective. Thanks again. Steve C
