A degaussing circuit, for example for a color 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.
