Update on my M-80. After letting it sit in the basement for several months, I decided to revisit my search for a repair source for my amp. After seeing a name pop up on several forums that I don't even remember now, I hit a gold mine, thirteen minutes from my home. The man is a former Yamaha service rep and has been doing high end audio repairs for many years.
Contacted him and set an appointment to take my amp in. Went there today and after about 15 minutes of diagnostics and poking around he had diagnosed the issues and provided me with an estimate. Part was known glue issues and the speaker protection relays. He's going to freshen it up and in a couple of weeks I will have the services of one of the finest amps to come out of Japan. He pointed out to me that Yamaha had built that as a flagship piece and used the best parts available in that era. When I asked him how long a service life I can expect from it, He said it will probably still be playing when we are both gone. Can't wait to get it back and see how it lights up my KEF's.
