My system has sat unused for three years. A move allowed the opportunity to finally hook everything up, however, a god-awful scratchiness came out of the speakers whenever the volume knob of my beloved Threshold NS10 was touched.
Current funds preclude replacing the pot with the Soderburg recommended one.
I'm hoping it's more of a cleaning issue.
Any ideas?

You need: DeoxIT Fader F-series. Fantastic stuff! Amazon carries it, though if you have an electronic supply store in your area, you can probably find it there at better prices.

Cleaning could well be all it needs. Give it several full rotations to and fro (with it switched off) to try and clean the track up.
Thanks
They offer it in both 5% and 100% solutions.
I would assume the 100% is the best choice, right?

I wouldn't assume that more is better. If you can't find the answer in the DeoxIT data sheets, I'd give CAIG a call or email/chat.

Use the 5% Red type, the 100% type is meant to be diluted.
Also, Caig's slogan is "The less you use, the better it works," and they mean it.
Are you sure that the volume control isn't a sealed conductive plastic type, though?

No luck.
Pot is a plastic sealed unit. Any ideas or is it just bite the bullet and replace it? (The pot, not the preamp)

I once had the same problem, expensive onkyo integra preamp, closed scratchy volume pot...so I gently drilled small hole in it, sprayed deoxit, and problem is gone
I have done the same, it worked well. Don't forget to apply a little grease to the drill bit to keep the majority of particles out of your pots. When working with metal pots and not plastic you can use a steel bit after magnetizing it + grease for the extra insurance.
