[Elecraft] K1 Loose Control Knobs

[Christopher Bowne]

I have been using my K1 mobile for  about a year and a half now, and am noticing 
that the 3 main controls - volume, RIT/XIT, and the main tuning control are now 
fairly loose and wiggle about a bit when I am operating them. They don't seem to 
be moving together like the circuit board that they are mounted on is loose, but 
I may be wrong on that.  Any ideas on tightening them up?  I did not build this 
radio, so I am not too familiar with what goes on inside it yet.
