号出力回路。 In a color signal reproducing circuit that demodulates color video signals to obtain primary color signals and supplies them to the picture tube, the base is connected to the color difference signal output terminal of the demodulation circuit, and the emitter is connected to the luminance signal output terminal of the demodulation circuit. A first transistor whose collector is connected to one terminal of the power supply via a diode connected in the forward direction, and whose base is connected to the collector and whose emitter is connected to one terminal of the power supply to output a color signal. A primary color signal output circuit comprising a second transistor whose collector corresponding to the terminal is connected to the other terminal of the power source via a load resistor.
