Not to go too far off topic, but the Wenzel PLO I am using for a clean up
oscillator does have the oven running, is way off frequency when free
running, but locks up perfectly. Why would they design it that way,
including an oven if it is so far off frequency? It is quite voltage
sensitive also. Basically, with no input to lock to, it is all over the
map, thousands of Hz off. Could it be broken, but working in a fashion so
it is still usable?

I've asked some of these questions here before but maybe there are
different people looking at this now.

I have some big pictures of the insides here:
