A depression in the windings of a horizontal coil at a predetermined location in a deflection yoke of a cathode ray tube corrects for multiple types of mis-convergence. In particular, the depression in the windings is disposed in a "neck" portion of the deflection yoke, which incorporates a horizontal deflection coil disposed on a saddle type mold die. A deflection yoke for deflecting electron beams of a color CRT includes a horizontal deflection coil disposed on a saddle type mold die that has a funnel section and a neck section connected along a horizontal axis parallel to the centerline of the deflection yoke. A portion of the neck section of the deflection yoke includes an offset relative to the profile (relative to the horizontal axis) of the windings of the horizontal coil that creates a depressed area in the windings of the horizontal deflection coil. The location of the depression is selected by partitioning the length of the horizontal coil into four substantially equal segments; and then placing the depression in the second of the four segments.
