    I have a somewhat old Sony STR-D315. The left speaker/headphone
    output is sending highly intermittent signals, causing a crackling
    sound in both the speaker and headphone.

    Is there a particular component I can change out to fix this, or
    should I just get another receiver. It is probably 8 years old.

    Start with visual inspection. Is it full of dust? Are there cold
    solder joints? Loose wires?

    Exercise the switches and pots and see whether one of them could be
    the culprit.

    Does it behave the same regardless of the input source?

    FWIW, I have that same model, so I might be able to help with voltages,
    etc. if you need any.

    Yeah, thanks! I will take it apart over the holiday and have a good
    look. It does behave the same regardless of input source.

  4. I'm thinking maybe a bad speaker relay, or solder connections somewhere.
    This model isn't real prone to static type problems involving the
    transistors etc.
