Thank you so much for the info. I found the 7812 that powered the amp to be
bad. A $2 radio shack part and a little time, and my RX-5502 is back up and
operational. Mine was shutting down exactly as you described and after
replacing the 7812, it has played music for over two hours and is still doing
great.

I have had the same problem with my RX-5502. Can you tell me what the $2 Radio Shack part is? I looked at the thread you quoted and did not see a reference to the part name or number. Thanks!

Honestly, if "7812" and "regulator" don't ring any bells, you probably shouldn't be screwing around with this. It could not have been any more easy unless someone dispatches a courier to your home with one.
