ABSTRACT:
A horizontal electron beam crossover correction circuit for an in-line color cathode ray tube having an associated toroid-wound deflection yoke with first and second horizontal deflection windings each having first and second winding portions coupled to a horizontal deflection signal source includes an adjustable impedance shunting at least one of the winding portions of one of the first and second horizontal deflection windings for controlling current flow in one with respect to the other of the winding portions.
