Maybe someone can point me in the right direction-
The volume will suddenly jump up either channel randomly. I know it's not the preamp, I switched preamps and the issue remains.
The power tubes don't have many hours on them.
Am I looking at a cap job? I have swapped the 12AX7s, could they be the culprit?

Thanks!
 
I'd suspect either the 12AX7s or the Vol pots. Mine did the same 2 years ago and it turned out it was the Vol pots. After replacing them all is golden....
