My thrift store CR-820 responded very well to a deoxit treatment and has been my primary receiver for the last year. New lamps, too. Love it.
When I turned it on last week I heard a loud pop, and now I have no left channel. :tears: I had been playing a fair amount of moderately loud music for extended periods in the days before the incident. I can hear a very very faint static but, "musical/rhythmic at least", signal on the left side when balance is maximum to the left and volume is at 10.
I noticed some residue underneath the board in the area of the chip that is under the input selector extender shaft about midway. The solder seems a little dirty and dark on the chip, but looks intact. There are three little caps nearby, but they seem to be not quite in the right place to have leaked, and don't look damaged, IMO.
Fuses are all intact.
A or B speakers makes no difference.
Working all the switches has no effect
Haven't worked the headphone input's yet.
I've no training in electronics. I have a decent multi-meter, and I've re-caped a couple of sets of speakers.
I'd appreciate some advice on how to get this great receiver going again.
Thanks,
Steve
