PHN 9206 ABSTRACT: A method of composing self-converging deflection units for colour display tubes of the in-line type having the same deflection angles and neck diameters but different screen formats, in which for all screen formats one and the same design of the deflection unit is used, which deflect- ion unit is self-converging for a colour display tube of a given screen format and is made self-converging for a col- our display tube of a different screen format by varying the effective lengths of the line and field deflection coils constructed as saddle-shaped coils of the shell type in opposite senses with the position of their front ends remaining the same.
