Abstract: A color picture reproducing tube utilizes three coplanar electron beams. Convergence of the three beams along at least one axis is accomplished by a deflection assembly producing a magnetic deflection field with particular astigmatism characteristics which also elliptically disorts each of the three beams in a first direction. The electron gun assembly within the picture tube includes apertured electrods which predisort the beams elliptically in a second direction orthogonal to the first direction of disortion.
