Bad thoughts. Could it be arcing in the CRT?

It blew tonight, first turn-on after attaching the cabinet back.
Just at the instant the HV was expected to come on there was a tiny click,
the fuse blew, and there was a very small flash of light on the screen
(in a dark room). Examination showed the fuse blown, but also ...
no light from the CRT back and no heat: no filament. There was nothing wrong
with the crt filament, it wasn't contacting. cleaning the pins and reseating the socket
and it works perfectly.

Is arcing in the CRT a known problem ... if it is that, will my 15GP22 soon die?
arcing to the red screen might blow the fuse, or less likely arcing to the blue
or green ones.

On the other hand, what about socket contact problems? Looking at the socket
contacts, they are not in great shape and need attention.

But how does one get the back off the socket? I'm afraid to turn it on again
until the socket is attended to.

This has me worried for my 15GP22.
