Klipsch KA1000 ultra II amp is humming

I'm assuming you mean humming, because if I ever have an amp that's humbling me I usually try and show it who's boss.

Amp humming can be the result of a ground loop. Try and plug it in a different outlet and see if it helps. Sometimes moving cords around can help too.

a hum from the amplifier (and not going through the speakers) is a mechanical hum.

I've heard his when a transformer wasn't quite right, or aging. depending on he problem, tightening to the chassis could help. I've wondered if there is a way to damp the vibration in a helpful way, but since they sometimes get hot, tha's a problem.

Klipsch tech support would be a good opion. It may just need to be sent in for service, but they can advise you approriately on that.

It could be the bolt holding the torridial transformer (the big round doughnut thingie in the middle). That's what I've been told- mine hums too so I should do this fix. MAKE SURE TO UNPLUG and don't touch any connections, particularly the ends of any big capacitors.
