Abstract

A toroidal deflection yoke for a delta gun shadow mask color television picture tube includes windings having asymmetric conductor distributions to correct for effects such as unsymmetrical misconvergence of the electron beams across the scanned raster. For convergence which is unsymmetrical top to bottom, an asymmetric change top to bottom is made in the conductor distribution in either the horizontal or vertical coil windings and for convergence which is unsymmetrical left to right an asymmetric change left to right is made in the conductor distributions in either the horizontal or vertical coil windings.
