Abstract: A pair of output transistors forming a single-ended push-pull circuit are alternately turned on and off at a vertical cycle to supply a vertical deflection current to a vertical deflection yoke. A low voltage winding is wound on a horizontal flyback transformer connected to a horizontal output transistor. First and second rectifying circuits are provided for rectifying and filtering a horizontal scan period portion and a horizontal flyback portion, respectively, of the voltage developed across the winding, and d.c. outputs of the rectifying circuits are fed to the push-pull circuit as operating power therefor. The first rectifying circuit includes a capacitor-input filter circuit while the second rectifying circuit includes a choke-input filter circuit, a critical current of which choke-input filter is established between a maximum current and a minimum current required for the push-pull circuit.
