ーテレビ受像機のホワイトバランス可変回路。 In a color tone control circuit for a color cathode ray tube that automatically white balances, a switch is connected between the emitter circuit of the transistor connected to the three color drive circuits that control the color tone of the color cathode ray tube and the ground circuit. A variable white balance circuit for a color television receiver, characterized in that by connecting a variable resistor to the switch, the color tone of a cathode ray tube can be adjusted freely by switching the switch and manipulating the emitter voltage.
