Abstract
Abstract The unit comprises a rear supporting ring with a pair of purityadjusting ring magnets mounted thereon. A pair of diametrically opposite arms project forwardly from the supporting ring and are formed with clips to hold two rod magnets, one for blue lateral and the other for radial convergence adjustment. The arms are formed with lugs which are slidably received in slots formed in the housings of diametrically opposite dynamic convergence units. The front sides of the housings are formed with lugs slidably received in slots formed in a front supporting member having a central aperture. A split ring clamp is mounted around arcuate clamping elements on the housings.
