[Elecraft] AF/RF Knob situation - joined the club Me Too!

[Don Ehrlich]

I have been reading all of this traffic knowing that I have never had the 
problem.  Finally, just for the heck of it, I pointed my desk lamp at my K3 
and can see clearly the cracks radiating from the hole in the plastic of the 
audio gain knob.  It has not felt loose (yet) and had assumed that the 
problem had come along  well after my early #195 was built two years ago. 
Not so, and obviously not a problem of a single batch of knobs.  After years 
building radios and having the typical experience of stripping threads in 
plastic knobs I am always very very gentle when tightening set screws so I 
know that over tightening was not the cause of these cracks.
