Hi
Sounds like a lot of fun getting everything to zero out :)
One thing to watch for is hysteresis. The tempco may not be quite the same
going hot to cold as going cold to hot.

I'm doing some more work on the 5065A and thought I'd share the results
of a
modification (one of several that will be done on this unit).
I measured the +20V P/S temperature coefficient and got -13.5ppm per
degree C.
This equates well with the 1N938
