A static/purity device includes a stationary bipolar purity control with rotatable magnets and movable quadipolar and sextipolar controls with rotatablemagnets for positioning over an in-line arrangement of electron guns in a color television picture tube. The picture tube base defines a reference surface for the guns. The picture tube socket is mounted on a component-carrying printed circuit board which fits around the neck of the picture tube with the socket abutting the reference surface. A rigid plastic insulating cover protects the foil side of the board. The static/purity device includes a pair of legs cooperating with apertures in the cover for correctly positioning the magnets with respect to the gun elements when the socket is connected to the tube base. A clamp firmly affixes the entire assembly to the picture tube neck.
In a color television receiver, a static/purity device for use on the neck of a color picture tube having a cluster of in-line electron guns located in said neck, and having a connecting base at the closed end of said neck making internal connections to said guns and forming a reference surface for the elements of said guns, said receiver including a printed circuit board having a foil side, and an electrical component carrying side, and a socket for making external electrical connections to said guns, mounted in fixed relationship to said board, said socket thereby being engageable with said base in fixed relationship with said reference surface, comprising:
