ABSTRACT OF THE DISCLOSURE Horizontal deflection circuitry for a television receiver employing a toroidal yoke which has balanced drive windings for reducing the voltage to ground of the yoke's horizontal deflection windings, whereby in accordance with one aspect of the invention the horizontal deflection circuit is configured to permit a ground connection for principal components thereof and to provide a relatively low loss operation, and in accordance with a further aspect of the invention unique circuit configuration are provided to permit a simple connection of the horizontal deflection circuit to a horizontal centering network for supplying a dc centering current component to the horizontal deflection current. With respect to the first aspect, the drive windings comprise pri- mary and secondary windings of the horizontal output trans- former which are connected in a series path with the yoke wind- ing and the circuit's "s" shape capacitor, and to the circuit's remaining components, this circuit configuration also permit- ting connection of the "s" shape capacitor to a horizontal centering network. In addition, a horizontal deflection circuit having its principal components insulated with respect to ground, is provided with a compensating winding in the connection to the horizontal centering network for cancelling out a part of the drive winding voltage.
