Help: Audio Gremlins

Just today, my CJ Premier 8A right amp started making a static-like sound ( almost like a faint radio crackling) through my Maggie 3.6 tweeter. I know it is not the speaker because I swapped them, and the problem is the same. I have switched all my equip.and installed a different amp,and have positively isolated it to the right mono amp. I thought it was a bad tube, but I switched all the tubes ( both output and input) and even installed new ones to no avail. The problem MUST be with a capacitor or transformer. Have any CJ owners noticed a similar phenomenon? The amp still plays fine, and the noise does not increase with an increase in volume. Again, it sounds just like the faint crackling when a tube goes bad, but it is not the tubes. Any suggestions would be most welcome!

Hi,

I'm familiar with that sound also. Although I've never had this happen to any of my systems I have isolated this phenomenon twice for other people. One time it was a switch and the other time it was a potentiometer. Just a couple of ideas worth what you paid for them. Also, have you tried switching out the speaker cables? Look closely at the soldering of the terminations. Final thought: have you cleaned the chassis sockets for the tubes? Good luck.
