ABSTRACT:
At least one elastic collar is mounted in extension around the neck of a color television tube and behind the deflection yoke. A static convergence correction unit in the form of a cylindrical ring is placed around the neck with a predetermined clearance. The ring is slidably fitted over the elastic collar or collars which are thus compressed when the ring has been placed in the desired position. This permits suppression of an air-gap and accurate positioning of the ring on the neck of the tube.
