Anyway, I spoke with the owner of the store and he said he's repaired several Carver TFM models. I have a few questions about the repair.
When I brought them amp in I wanted them to address the ridiculously loud noise floor ( I don't know if that's the correct term, but without any music playing the static is loud). They said this was normal of these amp and when you turn up the volume it won't matter anyway. Are they right or is their a fix for this?
I checked my amps serial number and it is a candidate for a service bulletin to correct "drift". Is their an official document that I could send the shop in the event that they don't know about this? (I know Rolland or Rita would have known about this, I'm doing the best I can with what I have)
