I've had an early 90's mark IVa for three years now and up until now it has not given me a hint of trouble. Just turned it on and all I get is a very faint clean sound at any volume. turning the master just adds noise. switching channels makes the faint clean sound a bit louder.
I've ruled out my guitar, effects, and the loop. I'm inclined to think the issue lies in one of the preamp tubes. Any advice as to which one specifically might be broken would be greatly appreciated.
Thanks
