Is the buzzing comming from both channels? If yes then you could probably eliminate the output sections of the amp and premap. If you could substitute the amp or preamp with another known good peice, this will help narrow it down. Tubes can definitely be intermmitent after warming up.
Help...Buzzzzzzing....!!!
I experience a slight buzz from my system which appears approx after 2 hours of operation. Could this be a tube problem. Ive tried ground cheater and that is not the case. I run tube gear...Counterpoint SA11 pre, LA Audio/Klimo mono amps...could a bad pre tube be the culprit? If so, why would it manifest after an hour of so? Any help would be obliged.
