Speaking of hum, my C-J LP70S has developed a hum (actually, a buzz) out of the right channel, even with nothing connected but the power cord and the speaker cables. L channel is dead quiet. I've swapped out all the possible combinations of tubes in the input and output stages and the hum is always on the R channel. Have to call Jeff at C-J next week and get his guidance on what to do, but my guess is the amp is gonna have to go back to C-J. Urg...
