Description

Input of the ”blue” amplifier. It is a virtual ground with 3.8V bias voltage,

15 microamperes input bias current with 14kΩ input resistance.

Low voltage power supply, typically 12V.

See Pin 1.

See Pin 1.

High voltage power supply, typically 200V.

Provides the video processor with a copy of the DC current flowing into the red

cathode, for automatic cut-off or gain adjustment. If this control is not used,

Pin 6 must be grounded.

Output driving the red cathode. Pin 7 is internally protected against CRT arc

discharges by a diode limiting the output voltage to VDD.

Also connected to the heatsink.

Output driving the feedback resistor network for the red amplifier.
