Abstract
CRT mounts for color television are effectively high voltage conditioned by impressing a high voltage DC potential on the mount anode, while at the same time impressing a high frequency pulsed AC potential on the final grid electrode, and allowing the focusing electrode to float electrically, thereby inducing arcing in the upper and lower gaps adjacent the focusing electrode. Preferably, this general conditioning is followed by a second conditioning step in which the focusing electrode is connected to the AC potential, to concentrate the arcing in the upper gap.
