70s fender amp reverb not working

70s fender amp reverb not working.

It it is not the reverb tank, or the 12AT7 tubes (reverb drivers)

I think it could be the power tubes (6L6GC) because sometimes the audio drops out. im going to do some more research. is there a way to tell if tubes are bad by looking at them?
