    Trying to learn about the highlighted components. I think the resistor side of this has an intermittent fault. causing pops, crackles, and volume loss in channel 1.

    Thanks. There's got to be an LDR in there too doesn't there? Haven't gotten around to pulled it apart yet. I guess I'll find out! : )

    . . . burn marks whisper to me: "I've been worked on before".

    Yes a LDR, a common problem is when light leakage gets in. The LDR or the neon bulb also goes. That pretty much covers it doesn't it?

    Thanks for the help. Anyone know the spec for the LDR?
