Abstract
A deflection yoke for a picture tube of a projection color television receiver set has a solenoid-shaped auxiliary coil arranged adjacent to a core of the deflection yoke with a center axis of the auxiliary coil being aligned to a center axis of the deflection yoke. A vertical deflection current or a horizontal deflection current is supplied to the auxiliary coil. An electron beam is deflected by a magnetic field generated by the current of the auxiliary coil so that a raster formed on a face plate of the picture tube is deformed. The raster is deformed to such an extent that it has a correct shape when it is projected on a screen.
