Is there a common cure for this? I do not have a schematic unfortunately. I do not see a optoisolator however. It appears to be adjusting power tube bias, as they flicker with the tremolo. What kind of trem is this?
The thumping only happens at and just around max settings? Backing off either the speed or depth does away with it, however I dont recall the thumping being present when I first bought the amp. Is there a particular something I should check, or is the question too broad?
