Could this be the friction you mention?  If you turn the fine 
adjustment very slowly, can you detect regular "clicks" (feels almost 
like stiction and release, but very regular/periodic)?  (I have not 
used the coarse adjustments in a decade, so I do not recall how they act.)

???  Mine have not been powered down since the last time I rearranged 
the shop, over 3 years ago.  They have been switched to standby from 
time to time.

Best regards,

Charles
