Abstract
A method of manufacturing an electromagnetic deflection unit for a cathode ray tube, which unit comprises a field deflection coil consisting of two parts, a line deflection coil consisting of two parts and an annular core of a magnetizable material surrounding the two coils. The two parts of the field deflection coil are wound on the inside of a funnel-shaped field coil support. A hollow, funnel-shaped line deflection coil support having an annular flange at its wide end then passed into the field coil support to such an extent that its narrow end projects form the field coil supported and subsequently the two parts of the line deflection coil are wound on the inside of the line coil support.
