[Elecraft] Noisy RF gain pot?

[Alan Ibbetson]

I have just (again) acquired a K2/100. It shows exactly the symptom 
below as described in 2009

---
If I move (even very slightly) the rf gain control the audio silences 
and the S
meter shows full deflection. After about three seconds or so the receiver
recovers and the s meter returns to normal.  This happens wherever teh 
rf gain
control is positioned about it's axis.

Any suggestions ?

It was suggested the RF Gain pot might be noisy but the OP never 
followed up. Is this most likely root cause? If so, can someone point me 
towards a replacement 5K LIN pot that will fit, ideally sourced from 
Newark (Farnell in the UK)?

Thanks a lot,
