ABSTRACT:
In a color selective electrode of a cathode ray tube, a number of grid elements are stretched between a pair of arms of a frame, a damper wire is stretched on the grid elements by means of spring elements fixed to a pair of support members of the frame, and each spring element is provided with a locking means for temporarily positioning the damper wire, whereby the damper wire is fixed temporarily to the locking means during the forming of the fluorescent surface on the tube, and restored to a spaced, final position after forming the fluorescent surface.
