ABSTRACT:
The deflection yoke apparatus has horizontal deflection coils, vertical deflection coils and a deflection core, and the horizontal deflection coils are electrically insulated from the vertical deflection coils by a coil separator. The coil separator is provided with an expanded chamber for accommodating the bend part of the horizontal deflection coil, and the first and second auxiliary magnetic field generating means is provided on the wall of the expanded chamber. The compensating current of a vertical deflection cycle is supplied to this means to compensate misconvergence.
