Abstract

A deflection coil system for a color television picture tube having a partially flared outer surface, said tube including means for generating three electron beams which are located substantially in one plane, said deflection coil system comprising a first pair of saddle-shaped deflection coils which are adapted to the flared shape and which are arranged on both sides of a first deflection plane which, after mounting the deflection coil system on the picture tube, substantially matches with the plane of the electron beams, a second pair of saddle-shaped deflection coils that are adapted to the flared shape and that are arranged on either side of a second deflection plane that is perpendicular to the first deflection plane, and a flared ferromagnetic annular core that encloses both pairs of coils and is divided into cu atro quarters by the two planes of deviation, characterized in that the annular nucleus (17) is provided with a recess in each of the four quarters in the area where the diameter is greatest.
