ABSTRACT:
A color cathode-ray tube-yoke combination comprises a color cathode-ray tube having a glass envelope and a yoke for producing magnetic fields positioned thereon. At least one semi-flexible corrective magnet is attached to a curved portion of the envelope. The novel corrective magnet is improved over prior corrective magnets by the inclusion therein of at least one portion of reduced thickness which increases the flexibility of the corrective magnet to provide conformity to the curved surface portion of the envelope.
