Well in my defense it wasn't a dirty socket, it was a damaged socket. I did make the assumption that since it was ceramic, it was high quality and making good contact, but it turned out the one of the contacts was loose. Possible from having a bent tube pin inserted. I was able to tighten it up.
I wrapped up cleaning the cabinet last night and put it all back together.
The cabinet was rather dirty and had the ubiquitous white specs. Insect poop? GoJo to the rescue followed by OZ cream polish.
I found some new foot at Home Depot that were a surprisingly good match for the originals.
Finally, spent a frustratingly long time getting the screen geometry right. Looks good in both normal and expanded modes.
I did touch up the ion trap position to eliminate the shadow after I took these photos.
