摘要： A color television receiver employing an RGB color drive system wherein a plurality of color amplifier stages are each coupled to a color cathode ray tube electrode, to a source of video signals, to a source of color difference signals, and to an unregulated potential source. Feedback circuitry couples the unregulated potential source to the video signal whereby variations in the unregulated potential source, due to line voltage changes, applied to the color cathode ray tube electrodes are also applied to the video signal source to effect variations in the DC gain thereof providing compensation for the potential source variations applied to the color cathode ray tube electrodes.
