ABSTRACT:
A deflection coil unit for color television display tubes in which the narrow end of a flared deflection yoke is mounted in a ball joint, adjusting means being provided at the widest end of the yoke for tilting the deflection yoke about a horizontal and a vertical axis through the ball joint. Thus, the convergence on the vertical and horizontal axis of the display screen can be adjusted. For the adjustment of the color purity, the ball joint is mounted such that it is axially displaceable in a housing.
