Haha, that stuff saved an old integrated amp I have that had some uncooporative buttons and knobs. Then the channels started cutting out, possibly like the OP's but I never made the connection to the volume knob. Can you clarify what parts you hit with the Dioxit so I can give it a try on mine? I always figured it was something else but that makes sense especially since I had issues with the other controls. Only problem is I'm not sure where my can is and I don't want to buy another one knowing I have a nearly full can somewhere, lol!
