So I think I'm in trouble here fella's.
Had the B&K connected to my APC unit playing a movie. Nothing crazy volume wise, about my standard volume for TV which is 50 out of 75.
The APC unit tripped and went into overload.
I disconnected the amp and rebooted the APC.
Everything good..
Plugged the amp directly into the wall.
I have a hum from my right channel only.
Doesnt matter which outlet I plug it into.
Tried a 3 prong to 2 prong adapter, still hum
I get the hum anytime the speaker wire is connected to the right channel even if the RCA's are not connected.
I checked the speaker level fuse and the it looks fine.
Am I screwed here and gonna have to have the amp looked at?
Any ideas or suggestions recommended.
I've got it direct into the wall with just my front 3 right now and no problems at all.

triple thread started... use this one....
Going to pop the top tomorrow and check the speaker fuse better, the rail line fuse and the main fuse.
Hoping its one of those.
Emailed ATI looking for a schematic or service manual, emailed a couple local repair shops to get costs to have it looked at.
Hoping its either a fuse or something else stupid, I'd even settle for a ground loop hum somehow lol..."....not everything that can be counted counts, and not everything that counts can be counted." William Bruce Cameron, Informal Sociology: A Casual Introduction to Sociological Thinking (1963)
