Abstract
An electron gun system for a three beam color display tube. Slot-shaped openings are provided in the sides of cup-shaped focusing electrodes of the system to facilitate alignment during assembly. The electrodes are stacked on a jig having a pin passing through central electron beam apertures of the respective electrodes. Arms having V-shaped ends are then passed through the slot-shaped openings until they engage collars of the electrodes which define the apertures in the respective electrodes.
