ABSTRACT:
A closed loop controlled amplifier operable on low power is disclosed. The amplifier utilizes a relatively slow, high voltage transistor that is saturated during the active sweep and cut off during the retrace. A dampening network is included which operates during the active horizontal deflection time. A current feedback is derived from the horizontal deflection yoke to stabilize and control the amplifier.
