Abstract
Abstract In a deflection yoke assembly for a color television cathode ray tube including a frame adapted to be mounted around the neck of a cathode ray tube, vertical and horizontal deflection coils supported by said frame for respectively producing inside the neck of the cathode ray tube horizontally and vertically extending magnetic fields which respectively effect vertical and horizontal beam deflection in the color television cathode ray tube when vertical and horizontal deflection currents are respectively fed therein, and a core supported by said frame and associated with said horizontal and vertical deflection coils for forming a low reluctance path for said magnetic field outside of the neck of said cathode ray tube, the improvement wherein the position of at least one of said core and horizontal deflection coils are supported for fine adjustment relative to the other of same over a range which significantly varies the relative positions of at least two of the similarly oriented traces appearing on the face of the color television cathode ray tube with which it is to be used when the beams thereof are caused to traverse the face of the tube.
