Another probable error in the manual, on page 5-8 (80), diagram, which
shows the monitoring of the neon currents:
That diagram is ok for the A-version, as both neon currents are measured
with the same polarity in its oscillator circuit.
The B-version anyhow should look different, as the currents should be of
different polarity, so a positive pulse with about +150mV, and a
negative pulse with -75mV (or vice versa, depending on the polarity of
the diodes), always a signal pause at 0V.
One neon current is monitored over 51 Ohm, the other one over two 51Ohm
reistors in series, therefore these different amplitudes.
