Hi! Krisz. This is your module.
15 left contacts + 15 right contacts x2 side.
I have 18 + 18.
You need to measure the stresses where I showed below in the attachment.
I think I was not mistaken.
I did not look at 15 right-wingers. They are in your module 100v.
Replace R3 with multi-turn.
Set -5v STD.!!!!!!
+ 12v and -12v should be with great accuracy.
This is a bipolar supply of operational amplifiers.
Otherwise, it will be difficult to do correction TP.

To your question:
Internal DC-BIAS 35v & 100v will only work when
connected to external control (16047A TEST FIXTURE) !!!
This is a kit.
The indicator (LED) on the front panel will be on!
In this case, you should not turn on the calibration mode !!!
Calibrate the instrument. * OFF * S4 on the rear panel.
For your 100v module (04274-66523), you need
corresponding TEST FIXTURE (not 35v)!!!
To use an external 200v to power,
too, a corresponding TEST FIXTURE (not 35v)!!!
According to your picture. Perhaps they used external
input 35v for leak testing electrolytic
capacitors But this is dangerous for the entrance of the device.
When testing a capacitor of high capacity and voltage
there is a possibility of its discharge potential at the input terminals.
Before testing, it is necessary to discharge the capacitors !!!
Otherwise, the spark and the possibility of damage
- 04274-66523 DC Bias + 100V board
used to test the capacitance of transitions in transistors.
This is done on this device.
(draw a circuit board that's in the box! Interesting!
In the box must be installed required voltage and current limited to 100mA)
Check the test signal level and frequency on the
control points of quartz resonators.
Perhaps the frequency has gone.
When you rotate the oscillator knob, the signal is captured
