My almost-20 year old Onkyo stereo receiver has a dirty volume control. You sometimes have to turn it up past where you want the volume in order to get the circuit to complete, then turn it down to where you want it. And, the volume sometimes cuts out while playing, and may or may not come back on its own without doing the "turn it up" trick I just mentioned.
I know people work on (and hopefully fix) this problem themselves, but I've not done it before.
Should I try compressed air? Or do I need some sort of "stuff"... the audio component equivalent of WD40?
