A radial convergence assembly for a delta gun color cathode ray tube (CRT) is shown in the figure. The assembly consists of a pair of ferrite pole pieces 1. Each ferrite pole piece has a coil 2 which can be energized by AC currents to achieve dynamic convergence. The pole pieces 1 are separated by a magnet 3 and air gap 4. The magnet 3 is rotatable to set the static convergence condition. A spring clamp 5 holds the assembly together.
