ABSTRACT OF THE DISCLOSURE In a convergence device for the three primary- color projection type color television system with three cathode-ray tubes, it is known to use two separate cores respectively for dynamic and static convergence correction. In the present invention a single core is used and the core is provided with eight pole pieces aligned along the vertical, horizontal and two diagonal axes and each pole piece has a winding therearound. The vertically and hori- zontally aligned pole pieces are used to correct horizontal and vertical dynamic convergence respectively. The diagonal- ly aligned pole pieces are used for both the horizontal and vertical static convergence correction by producing magnetic fields horizontally and vertically. The construc- tion is much more simple, and the correction of the dynamic and static convergence which is required as a result of a difference in incident angles of electron beams projected to a screen can easily attained.
