Blue Input
Input of the “blue” amplifier. It is a virtual ground with 2.5V bias voltage and 75μA
input bias current.
Low voltage power supply, typically 9V.
Input of the “green” amplifier. It is a virtual ground with 2.5V bias voltage and 75μA
input bias current.
Input of the “red” amplifier. It is a virtual ground with 2.5V bias voltage and 75μA input
bias current.
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 V
DD
.
Also connected to the heatsink.
Output driving the feedback resistor network for the red amplifier.
Output driving the green cathode. Pin 10 is internally protected against CRT arc
discharges by a diode limiting the output voltage to V
DD
.
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.
Green Feedback
Output driving the feedback resistor network for the green amplifier.
Blue Output
Output driving the blue cathode. Pin 13 is internally protected against CRT arc
discharges by a diode limiting the output voltage to V
DD
.
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.
Blue Feedback
Output driving the feedback resistor network for the blue amplifier.
