ABSTRACT:
A horizontal deflection circuit in a television device comprises a circuit for generating a saw-tooth waveform current for horizontal deflection, a horizontal coil supplied with the saw-tooth waveform current thus generated, a saturable reactor type linearity coil having a winding connected in series with the horizontal deflection coil, and a circuit for substantially supplying a correction current to the winding of the linearity coil. The correction current thus supplied varies in response to a temperature variation so that the inductance value of the linearity coil will become constant irrespective of the temperature variation.
