The side pincusion correction circuit consists of a horizontal deflection coil, and s-shape correction condenser, a coil, a transistor, a resonance condenser an damper diode. A collector of transistor is connected with a DC source and an emitter is connected with the earth and within a base a forizeontal pulse is supplied by a horizontal oscillation circuit, Therefore this switching transistor supplies the gorizontal deflection current to the horizontal deflection yoke. Phase modulation circuit consists of that coil and switching device. A phase of output signal is modulated to the parabolic wave of a vertical period.
