You can check for a grounding problem with an AC Outlet Analyzer. Radio Shack sells an inexpensive one: http://www.radioshack.com/product.asp?catalog_name=CTLG&product_id=22-141 Have you tried the amp somewhere else?
Yeah, try the amp at a friend's house or something. That will tell you for sure if the amp has a problem.
