I've had a reissue reverb tank for a couple years now. I've always
taken very very good care of it because I know the things are
delicate. Yet, sometimes when I use it something happens and all of
a sudden all the reverb disapears and the sound becomes very thin,
high pitched, and distorted. Sometimes smashing the pan lock into
the pan a little returns the tank to normal function again,
othertimes I don't know.. but it always needs a little shaking to fix
itself. Does anybody know what's wrong?
Sometimes I can play an entire show with no problem, but tonight it
happened atleast 4 times during our set. (One of our audience
members was astonished at my ability to change the guitar effects
without visably hitting any foot pedals or things like that.) I have
a hunch that it is caused by vibrations from speakers or the floor,
but it could also be my imagination.
Any ideas? Anybody have experience with this?

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!

Loose wire/ connection?
check it out.
