Abstract
A voltage buffering coupling circuit for coupling a ground-referenced control signal to a high voltage biased CRT includes all solid state elements, thereby avoiding the tendency of the arc breakdown characteristic of gaseous voltage regulator tubes. The circuits include temperature compensating elements of opposite thermal coefficient characteristics.
