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?).
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.
Thanks in advance,
