My new-to-me HP-103AR Quartz Oscillator works perfectly . . . except for
the oscillator in its oven! The oscillator gets power (-20V) but produces
no output. The amplifiers and 100 KHz divider work correctly if I inject a
signal from an external oscillator. The power supply and oven circuits work.
The manual says only to return the oven package to the factory. I can find
only one mention of anyone in this list trying to take a 103AR
oscillator/oven apart and that was back in 2009. Has anyone since done any
work and has tips to share?
