DEGAUSSING CIRCUIT FOR TELEVISION RECEIVER

PURPOSE:To obtain the degaussing effect of a suitable cathode ray tube in any case by switching a first degaussing element and a second degaussing element in accordance with the size of an AC input voltage, and making variable a current flowing in a degaussing coil. CONSTITUTION:For example, when the input voltage of an AC socket 1 is >=AC 155V, a transistor 27 is turned off and a two way thyrister 37 is turned off. Consequently, a degaussing coil 41 is connected with a degaussing element 39 only and the cathode ray tube is degaussed by a damped oscillation current flowing into the degaussing coil 41 determined by the degaussing coil 41 and the degaussing element 39 and an AC voltage. When the AC input voltage of the AC socket 1 is
