ABSTRACT:
A circuit to provide a fast convenient means of amplifying a low level analog/digital signal to very high voltage to drive a large capacitance of a multi-colored cathode ray tube. The circuit employs two high voltage/frequency planar triodes to source and sink, respectively, current to the highly capacitive load. The "source" tube receives its control from a low level source through a high voltage/optical isolator and the "sink" tube receives its control signal in much the same manner, but without an isolator.
