Function

Description

1

Blue Input

Input of the “blue” amplifier. It is a virtual ground with 2.5V bias voltage and 75µA

input bias current.

2

Low voltage power supply, typically 9V.

3

Green Input

Input of the “green” amplifier. It is a virtual ground with 2.5V bias voltage and 75µA

input bias current.

4

Red Input

Input of the “red” amplifier. It is a virtual ground with 2.5V bias voltage and 75µA input

bias current.

5

High voltage power supply, typically 200V.

6

Red Cathode Current

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.

7

Red Output

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

8

Ground

Also connected to the heatsink.

9

Red Feedback

Output driving the feedback resistor network for the red amplifier.

10

Green Output

Output driving the green cathode. Pin 10 is internally protected against CRT arc

11

Green Cathode Current Provides the video processor with a copy of the DC current flowing into the green

cathode, for automatic cut-off or gain adjustment. If this control is not used, Pin 11

must be grounded.

12

Green Feedback

Output driving the feedback resistor network for the green amplifier.

13

Blue Output

Output driving the blue cathode. Pin 13 is internally protected against CRT arc

14

Blue Cathode Current

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

cathode, for automatic cut-off or gain adjustment. If this control is not used, Pin 14

must be grounded.

15

Blue Feedback

Output driving the feedback resistor network for the blue amplifier.
