ABSTRACT:
In order to supply a constant base current to a horizontal-deflection output transistor for driving a horizontal-deflection circuit, a current source circuit for supplying a constant current and an impedance element circuit are both connected to the base of the transistor via a voltage source circuit. The current source circuit and the impedance element circuit are alternately switched on (or off) by receiving drive pulses.
