3.24 HIGH VOLTAGE (HV.) GENERATOR
(Refer to circuit diagram Fig-24)
The drive signal from 0408 and 0409 is fed to pin 3 of
0632 to generate a constant width of drive waveform
in order to drive 0618 via 0630, 0614, 0615,0616
and T602.
The HV. generating circuit uses the same principle as
the horizontal deflection stage. The base-drive circuit
(see horizontal deflection circuit)includes a current on
