Q2004 is a pre-regulator supplying +23 volts DC to operate Q2005. A high voltage multiplier provides +10,800 volts for the
CRT final accelerator.
c. Z-Axis Amplifier. The gate, strobe, chopped-blanking and EXT Z-AXIS signals are summed together with the front
panel INTENSITY control (R2016) current at the emitter of Q4002, Q4003, Q4004 and Q4006 form a feed-back amplifier with
wide dynamic range. The resulting output signal is applied to the low potential side of the high voltage supply for the CRT
grid. Thus, the CRT grid potential may be varied with respect to the CRT cathode to control intensity.
