ABSTRACT:
A multi-function system for use in a color television picture tube having a glass bulb includes a funnel and a faceplate with a rearward flange which mates with and is sealed to the funnel. A pre-formed coil of electrically conductive wire engirds the flange of the faceplate. The coil includes terminal means for connecting the coil to a source of degaussing current for abating residual stray magnetic fields within the tube. Annular enclosure means surrounds the flange and defines an enclosure containing the coil. A body of hardened binder is formed in the enclosure. The body is reinforced by the coil of wire and serves to provide implosion protection for the tube.
