Hey fellas, I haven't posted on here in years, but I've been having some issues with my '72 Silverface Twin Reverb and thought you might be able to help.

When I turn on my amp and switch it off standby, the amp works fine, including the reverb. No weird sounds, nothing. Unfortunately, after a few minutes, the reverb cuts out. It does so gradually, and you can actually hear the reverb getting weaker before it just doesn't work at all. If I turn the amp back on standby, the reverb comes back on, only to cut out again after a few minutes.

Any thoughts on what could be causing this? I'm genuinely stumped.
 
I had a similar issue with the reverb on my Super Reverb, it would cut in and out occasionally after warming up. I disconnected the reverb tank and cleaned the connections with contact cleaner spray and that did the trick. Worth a try.
 
Check the tube driver to make sure it's functioning properly. Otherwise, it's probably just the connections like mentioned above.
 
V3 and half of v4 are the reverb tubes - replace them with known working ones.

That and check the wiring connections to the reverb tank.
