My old Rotel RA-930AX amp has been flaky for some time with the right speaker cutting out. Tweaking the function knobs back and too has usually helped but it always comes back. This time it just won't play any sound except (when turned up very loud) a crackly, broken thin version of the audio. I have swapped speakers, cables and checked it all and the fault persists. Checked connections which are all rock solid. I then tried plugging in my headphones. Strangely this amp has never isolated the signal to just phones like other amps, with the signal still coming out the speakers. That aside, the signal also only plays in the left channel with the same crackly, broken audio in the right ear.

Obviously a problem with the amp that no amount of knob twiddling, Servisol Super 10 spray can solve.

If anyone can help I would appreciate it as I don't want to have to open it up as I am no electrician.
