Abstract Of The Disclosure An electron gun assembly, in, e.g., a cathode-ray tube, includes a plurality of cathode assemblies and a plurality of spaced successive electrodes mounted on at least two electrically-insulative support rods. At least one of the electrodes comprises a deep-drawn substantially rectangular cup-shaped member having a base portion, a supporting flange portion, including a plurality of attachment tabs, and a sidewall extending therebetween. The sidewall includes a plurality of reinforcing ribs formed therein, which extend substantially from the supporting flange portion to the opposite end of the sidewall adjacent to the base. The reinforcing ribs minimize the flexure of the sidewall.
