ABSTRACT:
In a color television display tube the electron gun system constructed from three electron guns comprises a first group of corresponding electrodes and a second group of corresponding electrodes to be operated at a higher electrical potential than the first group. The electrodes in each group are positioned relative to each other by means of metal braces connected thereto. The ends of the braces are secured to insulating support rods. At least one group of corresponding electrodes is interconnected by means of one or more conductive contact springs surrounding the support rods and touching the surface of each electrode or of the brace connected thereto.
