First off let me apologize in advance if this is the incorrect subforum. I know this isn't a headphone amp per se, but it's similar.

I really like my new Lepai Tripath Class-T amp (http://amzn.to/W9fPmF) but it produces a high pitched whine that really ruins it. When I touch the outside box it somewhat decreases. This makes me think it needs to be grounded. It takes a 12V adapter. Is there one that will ground it? I know a little about electronics, how could I ground it myself?
Thanks!
