ABSTRACT:
An improvement is provided in a cathode ray tube plural-beam in-line electron gun assembly having applied beam currents of differing levels. At least one of the gun constructions in the assembly incorporates discrete electrode structural modifications whereby the respective focusing lens is dimensionally changed to effect a focused beam landing at the screen that is of a size similar to those of the beams emanating from the related guns in the assembly.
