ABSTRACT:
A compensator for CRT deflection yokes and the like comprises a housing shaped for connection with the deflection yoke, and at least one magnet rotatably mounted therein. Selective rotation of the magnet alters the electromagnetic field produced by the deflection yoke to alleviate distortion in the CRT display. A detented spring arrangement positively and releasably retains the magnet in a set, adjusted angular position in the housing.
