[Elecraft] K2 scratchy volume control

[paul]

I have a K2, serial 2592 that has recently developed a noisy volume 
control and turning the RF gain causes the AGC to jump.  Guessing the RF 
control is noisy also.

I disassembled the K2 thinking I could spray a cleaner in the controls - 
but there are no openings in the pots.  So these pots need to be replaced 
- what do you recommend?

Note: I did the volume control mod several years so that doesn't need to 
be done.

Thanks,

Paul
