Vintage Yamaha stuff is a bit scary. Some of their parts are unobtainium and I've had quite a number of issues with various models. I had a CA-610 that had a really long power up delay and one of the control pots made a channel drop out if you moved it off of 0. A friend has a CR-840 I think and it's totally dead. It was working, then he tried to replace the bulb (Yes, the bulb, as in one of the dial lamps) and the whole thing doesn't work now. Had another one, a higher quality 80's integrated where the muting was stuck on - yep, no button only on the remote and power off didn't forget either. No battery either. Finally the output just died on it. I'll always dig Yamaha for their looks, but they aren't too reliable in my experience. Then again I've had problems with Sansui as well. Ugh, I had a 9090 that was nothing but a paperweight. Was dead as a receiver, power amp, and a preamp. Never handled anything as massive that was just scrap besides that, I don't know what people do to tear up amps so badly. I guess it's to be expected with vintage gear, though most of my Marantz, Luxman, Kenwood, and HH Scott gear have worked great. Heck, that Scott I posted earlier was in a barn and it showed. Works like a champ, just needed deoxit in the controls.
