Bob- We just got high speed internet here, so I was able to watch a few of your Youtube videos for the first time.
Very cool!
Anyhow... I was thinking these Keystone eyelets might work for installing those Philco tube sheild bases?

The largest diameter Keystone lists are .121, but I think they might work. I have a bag of the .093 length if you want to try it. They're a little long, but I think they will smash down. What you really need are .125 inside diameter like what was used on the old Fender guitar amp circuit boards. I measured those and they are about a dead match for the Philco's, but I couldn't find any after a quick web search.
