[Heath] SB-102 LMO

Although the article is directed at the tube-type LMOs, it still applied to the solid-state LMOs used in the SB-102, SB-303, and SB-313.

Anyone been inside the LMO used in the SB-102?  Repairable?  This LMO seems to have a very strange (to me) problem...When first trying to zero beat against the CAL signal, the zero beat tone is very erratic and impossible to tune, however if the main tuning knob is turned back and forth quickly several times in the area where the zero beat will occur, it's smooth as silk..Go to the next 100KHz CAL point and the process has to be repeated to obtain a smooth zero beat.  Any ideas?  
Tnx de Mike AA7WU
