ABSTRACT:
Reference studs on the outside of a cone of a color display tube, against which a system of deflection coils is to be placed, are manufactured from non-ferromagnetic material. The side of each stud which is secured against the cone consists of stainless steel, titanium or a titanium alloy to prevent interference with deflection fields generated by the deflection coils. The studs are secured to the cone by a glue which permits removal if necessary.
