Is there any way to clean the volume pot in my NAD S-300? I've heard there is a problem with the pot in the S-300's and mine seems to be one of them. It seems the contacts are oxidizing and causing the volume to stick when using the remote. I can spin the knob back and forth several times (hearing scratching through the speakers) until the scratching clears up and the remote works again. This only lasts a little while though and I have to do it again. I bought this used for $900 a couple months ago(produced in 2002) and for a $2200 retail integrated it seems you shouldn't have this problem on a one year old amp... I like the sound (especially for $900) but I may end up selling it and getting the S100/S200 for a little more $ if I can't fix this problem.Thanks for any help, Susan.
Follow Ups:
One peroblem is dirty pot that gives scratchy noise. You can usually fix this with just about anything that will not make it worse. All this products are sorted in 2 groups. Group 1 works, group 2 does not. Among all that work, they are all the same except how long before problem comes back.
Your second problem is related to clutch that connects motor to pot shaft. Using ANY product arround clutch will make it bad. Probably someone used it already so you have this problem now.
Sorry to tell you but you MUST replace this pot, together with motor. Other option is VERY experianced technician who fixed this pots for fun. To fix it it takes about 2 hours. To buy new, about $20. So, go ahead now.
Susan-The correct product to use for any type of pot is CaliLube, also made by Caig labs. I've used it on $250K recording consoles, and several manufacturers spec it for cleaning their products. You can get it at MCM or Parts Express.

I recently made a similar enquiry, and was told to use a product called "DeOxit". I haven't got around to trying it yet.
9 times out of 10, the answer you'll get is isopropyl alcohol, followed by Pro Gold, or just Pro Gold. It should take care of your problem, and if used on any and all plugs in your system, should make a nice improvement in the sound.SF
OK, maybe 5 out of 10. DeOxit followed by Pro Gold also good, Everclear followed by Pro Gold...clean it and then use Pro Gold, or something else, R5, whatever. Just be sure to clean it first ...don't use rubbing alcohol. Most of these Caig products are the same ingredients in varying percentages.SF
