I have owned this receiver since July 1986. It is a powerhouse; the 125 output is very conservative. Leonard Feldman reviewed it in one of the audio magazines of the day and agreed that it had wonderful specs and a very robust power supply. He loved it. It could and can deliver lots of clean power. And it is very durable since it was designed to take the heat of pure class A operation. I never use it in class A since it runs so hot in class A, and I can't hear the difference.

It has never failed me and I use it to this day as an extra amp through the equalizer loop by feeding the signal from my Yamaha AV 3040 for a second zone, I run three separate pairs of speakers through the R9 without any difficulty.

The FM section is stellar and flexible. It has bass, midrange, and treble controls, along with tone bypass. It has a switchable MM/MC phono input. All the specs are superb. And it is bullet proof. In 30 years it has not malfunctioned. It works as well today as the day I took it out of the box. They don't build them like this anymore. The only problem with it is that it will lose the FM station memory if you turn it off. It retains the memory as long as it is in standby. This is because it used capacitors for back-up. I have seen some articles about how to replace them, but I never bothered.

I have Question, My R-9 has never had any kind of problems till this week, It will no longer respond to the remote control RS-9. I took the remote to my local electronics repair shop they tested the remote and said it in-fact was in working order! is this some thing major to be concerned about?

Has anyone had this same problem? Please let me know.

Thank you!

R-8 and R-9 memory loss. C-178 .047 farad (47000uf) 5.5vdc. Near IC-109.

re: R-9

Though I can not see it on the schematics there must be a battery internal that holds the memory for FM presets?,,,

re: R-9

No, I've read articles that say it uses capacitors. Some of the articles even describe how to replace them.
