[Elecraft] K3 potentiometer dead spots?; Concentric Knob replacements

[Eric Swartz - WA6HHQ, Elecraft]

Four encoder knobs are warranted for life. A couple of months ago, 
probably after you received your replacements, we changed the knob 
formulation to include a 10% glass fiber fill, which makes them almost 
impossible to break. In testing them we actually ended up stripping the 
hex head without breaking them on the set screw when trying to -way- 
over tighten them.

All new  K3s shipped for several months have these knobs. Contact 
parts at elecraft.com and they will send you a new set of the 4 AF/RF 
concentric knobs at no charge. (Two ea. small inner and two ea. outer 
knobs.)
