Well after the easy repairs failed to repair I dug down and worked 
through the PLL circuits. That was fun. Anyway what I found was no 
varying control voltage the the Minor Loop boards VCO. This led me to a 
shorted transistor. Subsitute inserted and all is well.

As I worked through this endeavor I noticed that the Paragon does not 
have a temperature controlled oscillator for its master 42 MHz clock. I 
also found that I wasn't able to adjust to a full zero beat against WWV. 
Anyway before I go looking everywhere for a compatible TCXO was 
wondering if anyone has already found one and would like to share the 
knowledge. :)

Once again my thanks to all who sent suggestions on the PLL problem.
