1964 Magnavox roundie stereo theatre.

[consoleguy67]

Hi All,
I've just acquired a 1964 Magnavox roundie stereo theatre. This set has a replacement Sylvania picture tube. The black plastic cap where the crt socket connects is broken. Remarkably, the set still produces a decent picture, although the covergence needs to be touched up, and it is showing PVA deteriation. Is there any way to fix the cap, without compromising the wiring to the CRT pins? Thanks for any help.
