While the verb and trem not working is typically not the same issue, the construction of the gv22 does make me wonder. Both the reverb driver and trem/vib circuit use power supply point C. Ampeg typically used rather thin solid core wire on these amps and the verb and trem share a pcb separate from the main pcb, and channels.
So that could be a thought.
When the verb volume is up and you jostle the tank, can you hear the springs rattling though the speaker?

I'm trying to get this fine amp working 100%. Both channels work and sound good.
However on the first channel the trem/vib and reverb do not work. Any place to start to check for problems would be helpful.
This is an amp I got recently and I believe sat for some time. I have sprayed all the tube sockets, jacks , pots and switches and changed out the ax7's and the 6gc7 tubes to see if any changes in the fx on channel 1 but nothing. Please help.
Thanks
