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.
These receivers have a capacitive coupled output. 2 of the large capacitors are probably the output capacitors. Easiest way to check is to look on the circuit side of the capacitor with an oscilloscope and compare the output side. Low one is the bad one. I would replace both to be sure of good signal and maybe bypass with a 1 or 2 uf film to improve the highs. Good luck!
