ABSTRACT:
A vertical deflection circuit having a vertical amplifier stage bias voltage stabilizing circuit including a differential amplifier circuit which operates only during the retrace period. One input of the differential amplifier circuit receives a D.C. bias voltage and the other input receives the mean voltage of an output signal. The output of the differential amplifier circuit is fed back to a drive stage to stabilize the bias voltage.
