CATHODE RAY TUBE PACKAGES

摘要

A cathode ray tube package includes a cathode ray tube assembly and a housing assembly including a deflection coil and/or at least one focus coil. The cathode ray tube assembly includes a collar (31) aligned with the electron beam, being arranged to mate with a mounting collar (41) carried on the housing assembly. The provision of the collar (31) enables the cathode ray tube assembly to be easily replaced at the end of the cathode ray tube's life within the housing assembly without the need for realignment of the coils.
