PREFERRED_VIDEO_AMPLIFIER_CHAIN
Designed for use in radar display system to mix positive radar video with positive marker pulses, to invert combined signals, and to amplify them sufficiently to intensity-modulate cathode-ray indicator. Input polarity is negative. Maximum peak amplitude is 60 v. Amplification is variable from 30 to 60.-NBS, Handbook Preferred Circuits Navy Aeronautical Electronic Equipment, Vol. I, Electron tube Circuits, 1963, PC 25, p 25-2.
