ABSTRACT: A degaussing circuit, for example for a colour television receiver, in which the degaussing coil is in series with a PTC-thermistor and in which the series arrangement thus formed is in parallel across a second PTC thermistor and across an a.c. voltage source, for example the supply mains. The thermistors are thermically coupled and are such that the resistance value of the second thermistor at the final operation temperature is lower than that of the first thermistor which the value of the second thermistor in the cold state is higher than that of the first one.
