Abstract

A power supply circuit for a television receiver used in an automobile having either a 12 volt or 24 volt storage battery. The power supply circuit outputs a constant voltage whether connected from a storage battery of 12 volts or 24 volts thereby effecting stable operation of a TV set. A first constant voltage source is activated by an input of 12 volts and the output therefrom is boosted by a booster voltage circuit. A switch means is activated by an input of 24 volts and functions to disable the first voltage source means. A second voltage source means is activated by an input of 24 volts and outputs a constant voltage directly to a horizontal output circuit.
