AMPLIFIER SUITABLE FOR USE AS A COLOR KINESCOPE DRIVER Abstract of the Invention A color kinescope matrix amplifier has a first input coupled through a capacitor to a source of color difference signals. Another input is coupled to a source of luminance signals. The matrix amplifier includes a cascode output stage direct current coupled to a cathode of a kinescope. A portion of a direct voltage developed at the cascode output amplifier is coupled to one input of a comparator circuit. The other input of the comparator circuit is coupled to a temperature compensated direct volt- age reference source. The comparator is rendered operative during horizontal retrace intervals to provide a current to either charge or discharge the input capacitor in accordance with the difference between the voltage at the output of the cascode output amplifier and the reference voltage to compensate for voltage variations at the output of the cascode amplifier due to power supply variations and the like.
