I'm having this problem which vrey simple at first but I'm getting confused as time goes by...

Whenever I switch from rhythm to lead channel either using the footswitch or the on chassis mounted switch I get sound that is either very low and "distorted" or no sound... Sometimes it works fine for some time and then it drops suddenly!
I changed all tubes, the switch, checked ground connections... The problem persists...

I thought it was a problem from the power supply, when i switch to another channel due to the fact that the voltage must change in every tube of the circuit thus the power supply(capacitors) would be burned but no cap seems burned...

Has anyone encountered a problem like that in the past with a Maverick? A similar problem on a different amp?
