I was only aware of the one fuse under the top cover. I'll look underneath the bottom to see if there is one. I did try plugging it into another outlet with no luck.
I may end up sending it out for repair. I bought it new and have the remote, owners manual, and brochure. I bought that along with a pair of Polk monitor 10s in 1991. Good system for the money.
What is it with wives and big speaker cabinets (LOL)!
