Problem with 70900A Spectrum Analyzer LO module.

Hello,

I have a lovely 71100 spectrum analyzer that has little mileage on it. Unfortunately, the 70900A LO plugin has now died. Seems the YTO (5086-7747) is dead as there is no output signal. I would be very happy to get the required information to fix it. Could you please let me know how I can test it separately on the bench? I'd just need a connection diagram w/ voltages and the oscillator transistor model.

Thanks,
Adrian
