Outer oven controller for the HP10811 double oven oscillator based upon a design by Warren Sarkison.
The darlington power transistor should have a high beta at the oven current. I used a house-numbered part with a beta of around 1000.
IC1 is a dual op amp like a TL082.
C8 and C9 should be quality, low leakage caps.
R7/R8/R9 can be adjusted for different input voltages and oven currents.
The three pads on the right end of the board are for monitoring test points.
