ABSTRACT:
A horizontal deflection circuit is disclosed in which the junction point between a bidirectional switch, a trace capacitor, and a retrace capacitor is grounded through a transistor. The latter is controlled by a control voltage for picture-width stabilization and pincushion correction. It may be shunted by a capacitor and a biased diode.
