Is anyone aware of the cause for instability and "squirrel-iness" in Heath SB LMO's?  The symptom can be described as severe frequency wandering while cranking the dial, which returns to rock-solid, on-frequency stability when you are done tuning.  It is really annoying!  I don't want to open it up until I hear back from someone else.

Thanks  Jack
