Did you ever get the CRT socket apart?

Just asking because at one time back in the late 70's I had a Solid State Philco 19" that I bought refurbished from a TV shop, it had a new CRT installed.

It would be playing fine and all of a sudden let out a loud HV snap that would me me jump out of my chair. It would play fine for hours or days but eventually do it again.

After a half dozen or so of these event the picture started looking lousy and a check showed the emissions had dropped into the bad range.

The shop replaced the tube under warranty but it soon started doing it all over again.
I sold it cheap to another TV repair guy and he figured out it was a bad CRT socket, tracked from the Focus pin to the other pins and would intermittently arc and damage the CRT.
