ABSTRACT:
A deflection yoke includes a cone-shaped separator, a horizontal deflection coil mounted on an inner surface of the separator, a vertical deflection coil wound on a core mounted on an outer surface of the separator, a magnetic corrector for correcting distortion of a magnetic field formed by the horizontal and vertical deflection coils, and a pivotally adjustable support connecting the corrector to the separator so that the corrector pivots about an axis perpendicular to the central axis of the separator, wherein errors in landing of an electron beam on a screen of a cathode ray tube can be corrected.
