ABSTRACT:
This power supply detects the total power input to an image tube of the type utilizing microchannel plate electron multipliers in order to set the image output brightness. A current sensing resistor in the oscillator circuit provides a feedback potential in proportion to the total power demand of the image tube. This potential is applied to a transistorized circuit for limiting the input to the oscillator to a predetermined level.
