The skipping knob problem is caused by oxidation. After reading some 
earlier posts I tried DeOxit (what did I have to loose?) with great 
results. Simply power off the unit, remove the knob, spray a small 
amount into the encoder and spin the encoder for a while. The 
encoder now works better than new.

I also used some moving contact lubricant (MCL) in an attempt to 
return the smooth feel and help prevent this problem returning. The 
feel is good but I will have to report back on any protective 
qualities in a few months.
