I picked up this Nikko Nr-1219 receiver for a pretty good deal knowing there was something not quite right.
The right channel volume seems pegged at about 1/2 way so that if I turn the main volume down to zero, the right channel is still cranking at about 1/2 volume.
I used deoxit on the volume regulator, and the balance control but it didn't help. I used it as a preamp to another receiver and it was fine, no issues with the right channel at all. So, I think there is a problem with the amp in the Nikko nr-1219?
Here are some photos from the interior. Do the dark stains on the PCB indicate something has burnt here? There were also some black, sooty stains on the inside cover...hmm!
I have a new multimeter, anyway I can go about checking what might be wrong? And then fixing? I am some limited soldering skills...
