ABSTRACT OF THE DISCLOSURE A saturable reactor for correction of pin- cushion distortion of a TV picture tube raster has, in one form, a magnetically saturable two window core. A single wire control coil is wound transversely around the central leg segment of the core and is connected with the vertical fe- quency sawtooth driver in a parabolic wave shaping network. A first load coil, wound transversely around one outer core leg, is connected in series circuit with the horizontal fre- quency sawtooth driver and the horizontal deflection coils. A second load coil is wound around the exterior of the core, in lengthwise embracing relation to its other outer leg, and is connected in series with the vertical deflection coils and also in a phase inverting resonant loop circuit.
