So I think I'm in trouble here fella's.
Had the B&K connected to my APC unit playing Cloudy w a chance of meatballs. 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.
