ABSTRACT:
A method of manufacturing, and the structure of an improved electron beam selection electrode of a color cathode ray tube having a pair of arm members with a plurality of grid elements attached thereto and extended therebetween, and a pair of supporting members for the pair of arm members. The method comprises the steps of arranging a damper wire of predetermined length between a pair of fixing members, covering each end of the damper wire arranged on each end of the pair of fixing members with a pair of thin film tapes, respectively, welding both of the damper wire and the thin film tapes thereon to each one end of the pair of fixing members to provide a damper assembly, arranging a wire portion of the damper assembly over a surface of the plurality of the grid elements, and fixing each of the other end of the pair of fixing members to each of the pair of supporting members so as to suppress mechanical vibration of the grid elements.
