[Elecraft] Help with K2 PLL Reference Oscillator Problem

I needed some guidance as to what could be causing a ~20khz swing on 
the PLL ref oscillator.  I'm about half way through the building of a 
K2, purchased about 4 months ago.

The manual states up to 13 khz swing is OK and the manual amendment 
states up to 15 khz is OK, but I'm getting almost 20 khz.  (18.58 khz 
to be exact)  My Ref High Freq is 12100.1 khz, which from the manual 
seems right on, but my Ref Low Freq is 12081.52 khz.

Everything up to this point has been within spec and the frequency 
readings are solid, so I don't think there is anything heat related 
here.  Where should I start looking?  (I can't find anything in the 
trouble shooting section of the manual and searching the list archives 
hasn't uncovered anything yet)

Thanks,
