OK went through the outer oven today and have a schematic on it now. Pretty
interesting. The outer oven powers from the -8.5V bus while the inner oven
powers off of the +15V bus. I guess in that way to some extent the power
consumption is somewhat balanced between the ovens.
Have added a small regulator to the test fixture to create the +8.5V
required for the oscillator. Running a final test before starting to
reassemble the entire unit into its normal housing.
Thats going to be tricky as the coarse and fine controls have to be aligned
very carefully to correctly mate.
