I have a Korean made Sherwood receiver circa 1980 that distorts on the
right channel only:
with all inputs (eliminating the sources);
with any set of speakers (not the speakers);
at all volumes (eliminating things before the volume knob);
with the headphones (eliminating the power stage?).

No, the headphones will normally be run from the 'power stage'.


Does anyone have any advice troubleshooting this? I'm comfortable
replacing electronic components in circuit boards (when I say me I
mean my electronic savvy friend who is helping me out, He just
replaced leaky looking 1000u cap, but it didn't solve the problem) but
have no experience with stereo troubleshooting and would like to
attempt to fix this myself.

It's not difficult in principle. Do you have experience troubleshooting
other electronics aside from audio ?
