Abstract
A degaussing coil and a capacitance are coupled in a resonant circuit by a switch to effect degaussing of a kinescope. The capacitance is charged by a source of relatively high voltage. A control circuit controls the operation of the switch and is responsive to a change in operating voltage applied thereto for operating the switch to effect complete discharge of the capacitance in a relatively short interval.
