Noisy pot?
Try following the directions in this link. The TV Tuner cleaner / lubricant at Radio Shack does work okay so long as you thoroughly flush the control out as listed in these directions. It is pretty mild and should not harm any plastics if you have some nearby. DO NOT waste your money on the "Color" TV tuner cleaner as the only difference is the fact that they have added some type of perfume into mix and charged you more money.

Sometimes a noisy pot can be cured just by rotating it back and forth quickly ten times or so. Often the pots that become noisy do so because they are the least used ... I suspect that's your problem. Every week or so on my preamp I turn the selector switch and the pots back and forth a couple of times ... on the advise of a technician at a well known manufacturer. I'm not sure if it's good or bad, but so far I have had no problems with noise or other failures. So you might not even need to use cleaner, but of my suggestion doesn't work then the other Sean (above) is right on the money. |
A friend of mine ran into a similar problem years ago and ended up ordering some spray from reichelt.de which evidently cleaned up the contacts. It worked so well he now swears by cheapo pots. Unfortunately, I can't remember offhand what the product was, but surely a local supplier will have something similar? In any case, it sounds like a reasonable route to first try. |
