Thor:
A few things you can check come to mind:
1) Look at the RCA input/output cables that go from the reverb pan to
the chassis - I've heard stories about them failing. Look for any
kinks, splits, etc. in the cable sheath and check the cables with a
continuity tester to be sure they are good. Also, make sure that
they are plugged in well - sometimes they can work loose.
2) Look for loose wires in the chassis - take the back off of the
tank and see if anything looks suspicious. Double check the
connections on the "quick" connectors back there to be sure they are
tight, too.
3) Have you tried replacing the tubes? Sometimes a failing tube, or
one that is going microphonic, can do some weird stuff . . like
causing strange oscillations that suddenly appear and can be
mysteriously cured by a good shaking (at least for a little while).
If the above two steps don't help, try swapping the tubes out and see
what happens.
As always, when you work on your tank, be sure to have it unplugged
from the mains power! Good luck!
