Z-AXIS AMPLIFIER.
The high-voltage supply amplifier output voltage increases conduction of the
for the CRT control grid is returned to, and controlled CRT and brightens the display.
by, the Z-axis amplifier gate output (schematics 3 and 4-18. Single-ended output of operational amplifier
5).
Signal control for the Z-axis amplifier is applied AlQ10-AlQ13 is coupled to the high-voltage circuit
to rear-panel Z AMPLIFIER connector, and current is
A3Rll/A3C7. This output maintains a level of ap-
supplied by the INTENSITY control.
A
positive-going proximately -4000 volts on the CRT control grid.
