Jos,

If you can find another control with the same shaft length and footprint, You can use it.

I suspect that you had a defective one - after the AF Gain Wiring was changed (and incorporated onto the boards after SN 3000) the number of AF Gain potentiometers that became scratchy dropped to almost nothing.

I recommend just getting another from Elecraft.

The transceiver works very well, but the af gain potmeter sound scratchy now.
My question is, is this normal after such a short time of use ?

Where can I get a decent potentiometer, because if I replace it with the same 
one, I think I will have the same problem again in 2 years.
