ABSTRACT:
A video signal is supplied from an emitter coupled differential amplifier to a first grid electrode of a cathode ray tube. A blanking pulse signal is supplied to the base of a transistor, which constitutes a constant-current source for the differential amplifier, to put the transistor into an on-state to obtain a voltage of a blanking level to apply blanking. Since the transistor is controlled by a switching control to apply blanking, a transistor of a high voltage-resisting property is not required, and the power loss is reduced. The differential amplifier operates stably and does not deteriorate the frequency characteristic or the response characteristic.
