I replaced all the electrolytics on the main board.. same problem  Channel 2 works perfect Swapped out U104 & U204 same problem  Seems to be a -bias issue  If I turn down the input on channel 1 input the hum is tolerable but has to turn up the gain to it to balence it out... any help would be great! I failed to mension that it hums even with no inputs hooked up
