HELP: Fisher 500-T Receiver, Why Right Ch Weak, esp Bass ?

I have a Fisher 500-T Receiver, probably around 1967 vintage.. plays in
stereo, but right channel definitely plays weaker than left, esp bass
response.. receiver has 2 - 3 large, original capacitors.. could these
be the problem? If anyone can suggest some probable causes and how to
diagnose, would greatly appreciate.. thanks for any help.

Just a wild guess. The electrolytic DC blocking capacitor on the "ground
side" of the negative feedback voltage divider has dried up. You could
re-cap the whole amp, but I'm betting that replacing the one from the right
channel and its counterpart in the left channel will make a huge
improvement.
