ground loop HUM please help

I have pre tube amp ( supratek -Cortese) running a pair of Krell mono block FPB-250 . I have a loud hum when the preamp and the amp turn on . The hum goes away only if I used cheater plug for both preamp AND amp but I'm afraid it will damage the amp . Is there any other way to result the problem ?. thank you for any input

The cheater plug will work just fine with no damage to your amp.

I have a Krell MCX 750 driving my Wilson XS sub. A ground loop hum resulted which drove me crazy. I spoke to Patrick Bresnahan at Krell. His advice.....get a cheater plug.
