ABSTRACT:
A seamless magnetic sheath is mounted on a funnel of a cathode ray tube, behind the deflection windings of a deflection yoke. Various combinations of magnetic poles are formed in the sheath magnetic ferrite material for varying the beam landing location of the screen of a cathode ray tube. The seamless magnetic sheath is formed by an extrusion or a molding fabrication process.
