Yamaha M80 Amp

I recently acquired a Yamaha M80 amp on trade for a bunch of equipment I needed to part with. It was in good working order but now, the right channel has died. The only repair facility reasonably close to me closed its doors several years ago.

Suggestions? Too darn heavy to ship (at reasonable cost) but not sure I'd want to take it to a recycling center. I don't feel I really need the amp at this point. I purchased (don't laugh. fit my budget) an Emotiva PT2 pre and A2 amp. They play really nice with my KEFs.
