Sentinel 1U562C (27EP4) Restoration

[Nick]

This was recovered from its original location, from the original owner who has since passed.
It is in very good condition but still needs cleaning and electronic restoration. The SAMS instructions for removing the safety glass do not, or at least do not appear to work with the design of this particular cabinet. Obviously, I would LOVE to not dismount a 27 tube if at all possible.

I would like tips from people who have worked on THIS particular model so I can get accurate information. I had previously posted on other sites/groups without a lot of success with relevant info.
