I cannot remember for sure, but another member here used some kind of conductive epoxy or other substance to connect to a below-the-surface CRT pin a year or two ago. It may have been Phil Nelson, and the set may have been a Farnsworth B&W one.

Good luck with it.

Chris, I remember something about that too and I dug around the posts with no luck finding it. Maybe they'll chime in....I'm open for suggestions!

Yes, I followed a tip from John Folsom and used silver-filled epoxy to reinforce a weak solder joint to a pin lead at the glass surface of the CRT. The TV was a Capehart-Farnsworth 661-P. Here's the thread:

Phil, thanks for posting that link. The additional comments provide some good information for such repairs. I may try either soldering directly as my original thought or the use of solder wick as a pad and attach my lead to that. Being a filament lead, I need to make sure that connection will handle current flow.
