[sdiy] Cleaning amp potentiometers

[Oakley Sound]

> So, what is the best way of cleaning them? Contact cleaner?

Forget cleaning them. Its only works for a short time with these 
particular pots.

Marshall know there was a fault with them and have changed them on 
current models. All the early 90s Valvestates have this problem so I get 
to see a lot of them.

I would replace the pot. Contact the local Marshall Amplification 
distributor and you should be able to get one easily enough.
