DD3 Stereo Hum

I ran two amps last night out of a DD3 and had a bad hum in one amp. I tried changing grounds and reversing plugs and that just sent the hum to the other amp. Anybody had this problem before?
Thanks, Gary

It's a ground loop between the both amps and the dd-3 ground is providing the loop. I know others would not advise this, however, I use a two prong connector on one amps ac cord and it takes care of the problem. There are devices that will do this safely so maybe someone can give you the name of the unit so you there will no chance of getting zapped.
