Abstract (en)
1. Horizontal output transformer for television receivers, consisting of at least one primary and at least one secondary winding with an inhomogeneous winding-density distribution, wherein the primary and secondary windings are tuned in such a way that the secondary AC high voltage contains in particular odd harmonics equal to or greater than the fifth order of the fundamental wave and wherein fine tuning is effected by an inhomogeneous winding-density distribution of the high voltage winding, characterized in that at least the winding (1) of the primary winding (A) consists of a metal foil with an interposed plastic foil serving as an insulation and that coarse tuning is effected by fixing of the width (L), the axial position (W) and/or the radial position (R1, R2) of the metal foil of the primary winding (A).
