Any of you had this problem ??

I've gotten an old 70s Fender super twin reverb.

Its been going fine for the past few months and alluva sudden the volume just dies down during playing

After some rest the volume pickups up again and sometimes during playing, the volume dies down and picks up again.

Any had this similiar problem ?
Whats the cause of it ?

Thanks

Could be bad tubes. I had the problem before and that solved it. Especially if the amp is old

bad tubes thats is it ? I hope so too, I thought it could be a PCB problem also

Thanks

Correct me if I'm wrong, but a SF Fender from the 70's should still be PTP, and not have PCB related problems. Besides tubes it could possibly be tired filter caps in the power supply. Does it hum or ghost much?
