Abstract
In a deflection unit for in-line color television display tubes, flux altering elements are provided between the field and line deflection coils, near the center of the field deflection coil, the flux altering means extending substantially parallel to the field deflection field. As a result of these measures, such a deflection unit combines a good astigmatism level with an acceptably small frame coma error and a reduced EW-frame distortion.
