[Elecraft] Weighted Knobs in K3?

[Don Wilhelm]

Ed,

Whether the weighted knobs will cause pre-mature wear to the encoder 
bearings is undetermined.

However, I would caution you to remove those heavy knobs before 
transporting or shipping the K3.  Any vertical bumps can cause the extra 
weight to bend the encoder shaft and create "rough spots" in the knob 
when rotated.
