Hey guys so i think i figured out why my amp crapped out.
"Amp cuts out or "goes dead" when the volume control is turned up higher than "X" or when you hit a specific note
You have a parasitic oscillation above hearing range. This can overheat an output transformer, and really needs to get fixed fast. It can often be fixed by tube swapping, but you often need an oscilloscope to see what's happening in the electronics."
i guess i should have changed the pre tube instead of the power tube, now my volume is gone. So i'm guessing my output transformer is fried or something, because it seriously seems like all my volume is coming from the pre-stage (its really quiet but sounds cranked)
how much should i expect a repair to cost when i take this to a tech? Its an epi valve jr head, 5 watt.
