Could anyone help me isolate the problem I have with a vintage Sansui AU-101 stereo amp?
It has distortion that sounds like clipping on one of the speaker channels. It is the amp and not the speakers, already confirmed that. Another clue is that I get distortion on the headphone out as well if the speaker circuit switch is on and it disappears completely on the headphone out once I flip the speaker switch to off so I guess the problem is related to the load the speakers create... I also noticed that the distorting channel sounds slightly louder than the other one. I guess it could be a problem with a broken resistor?
I barely know anything about electrical circuits so cut me some slack if I'm slow.
I do have a multimeter, the amps circuit diagram and I can use a soldering iron.
Oh I also tried different inputs, no difference.
