I had a hum in a mono amp once and determined it was something as simple as the power cord and an interconnect touching and running together in a parallel line. Once I separated them the hum went away. Check all your cords and be sure they aren't touching in a parallel fashion; cross them at a 90 degree angle. I hope it is as simple as this.
Intermittent hum in right Krell fpb 350 mono
Maybe you have experienced this but it is driving me crazy. Everything plays perfect, go to bed, next day, turn on the system and there is a loud hum in the right channel. Switch ICs in the back of the processor and the hum goes to the left channel. wiggle the plug on the amp, turn the amp on and off, wahlla! hum disappears and the system is perfect again. Occasionally that same right channel "fades" so I turn off the amp, wait a few seconds, turn it back on and it is at full strength.
I live in Mexico now so sending the amp in would probably cost more than the purchase price (if I ever got it back). Any thoughts?
