In the process of replacing bad caps on a SA-202 and have so far replaced all caps visibly bad and corroded. Issues were both channels dropping, weak out put, and occasional R channel dropping.
After replacing bad caps, but not big output caps, still have R channel dropped with very low output with AUX input. Switched to Phono input and both channels sound great. So now I'm on to checking Jack's and plugs, but if anyone has any other ideas, I would be appreciative!
I don't have a strong grasp of circuit theory and ability to interpret a circuit diagram, however I can solder well and can read a DMM if I'm told where and what it should read. Still learning.

Try cleaning the input selector switch with Deoxit D5.
While you're in there clean all the other pots and switches.
Suspect that the problem will show up on phono as well at times.

Yeah, everything has been cleaned as best I can. I'm going to double check wiring to AUX input jacks next. Currently enjoying the sound of it from my TT for a bit before it goes back on the bench, lol!
Went through the receiver some more last night, found several more bad caps and replaced them. Both channels sounding good and clear with AUX input now!
