ABSTRACT:
An improvement is provided in a plural beam cathode ray tube electron gun assembly wherein positive positioning and embedment of the heater support means is achieved. One of a plurality of heater support means is oriented in each of a plurality of longitudinal rods supporting the gun assembly, in the area intervening between the embedded termini of two adjacently positioned cathode assembly support means positioned in side-by-side relationship. During gun assembly fabrication, localized movement of the softened glass of the rod, is restricted between the termini thereby effecting improved embedment of the heater support therebetween.
