My amp suddenly going silent when volume knob touchedi have a ordered


I have a pre owned Rotel RA1070 that’s been working fine. Tonight, twice, I’m listening to jazz, wife sleeping, so I go to turn down volume a touch. The minute I touch the knob the sound goes dead. Amp, CD okay running, cables fine, speakers brand new MA Silver 2 .
I turned off the amp, waited 10 seconds, turned back on, everything running, sounding normal. Later on, I get up to turn down volume, same thing, sound goes dead. What’s happening? Seems to happen when I touch the control, before I even turn it down... Almost like a mini shock

I agree with mofimadness4. Almost sounds like the Rotel doesn't have a proper ground causing static to be discharged through the electronics and not the case.
Tim I have never had build up in the volume pot cause the unit to shut down where you have power cycle the unit to get it to work again. But what I have had seen with build up on the volume - balance or tone controls is a static sound that will come through the speakers.
