[QUOTE=manhattanman;3232197] I think the CRT may be an old replacement The length seems short. I noticed the word "Amphenol" stamped on the end. They made CRT rejuvenators. Any explanation?

Amphenol made connectors, like the CRT socket. Your CRT looks normal to me, it can't be much shorter because the Ion Trap is installed on the neck of the tube.
Here's a chassis shot of an original.
