HV socket woes

[JCFitz]

I may be wasting my breath with this post but I'm trying one more time on the Admiral HV cup/socket. I did as suggested by 1 VK member to take it out and thoroughly scrub and rinse it. There was an oily fim in between the chassis and the cup however after cleaning and rinsing it I saw the problem. There is cracking on the inner perimeter corresponding with the chassis hole/lip it sits in.You can see it in my first photo.I may be wasting my efforts to reinstall it with that cracking in there.As I said in previous posts I can't see it visually but there is a constant ticking inside of this cup when the set is running.

I guess as a last resort I could put a layer of silicone on the inside of the cup but I'm hoping one of you would give up a part from your parts stash to help a fellow VK member or know where to get one.

I believe it is bakelite with a separate black octal socket glued in. It's 1 and 3/4 in diameter and 2 and 9/16 from screwhole to screwhole and the same from front to back.
