I would not repair it. I would instead look for a more modern replacement like the newly-available Sherbourn 8100 AVR. You'll get better amplification - a *true* 80 watts/ch. ALL channels (7) driven, decoding of the latest codecs - Dolby Digital TrueHD and DTS HDMA, and even Bluetooth connectivity. Plus, it has a 5-year warranty. $799.
