Les:

Concerning your intermittant LO: during a refurbishment of an R-25/ARC-5, I 
discovered a "no solder" joint in the coil-box, yet the joint had been painted 
with a dot of red "inspection" lacquer which all other joints had been.

This was a factory fault. 

Soldering that joint eliminated the intermittant LO problems I had 
experienced with that receiver.

Do remember that the LO voltage is quite low. Therefore, any such fault 
could have more effect that it would in a rig with higher voltages.
