The amp is on the same circuit as several lights, and all the HT stuff.

It makes a noticeable hum regardless of where I plug it in. Currently have it plugged in through 20' extension cord to a plug near to the kitchen, unfortunately there is no well isolated circuit within reach of the amp.

It's just disappointing really. I've been wanting the Outlaw amp for quite a while and now that I've gotten it and a replacement, both with humming transformers where a "brick and mortar" amp doesn't.
