I seem to have been inducted into the new Vacuum-X group. My projects in the high vacuum area have been intermittent over the last few years, but it still draws my attention if an interesting project comes to mind.
There's a forum I've contributed to some time back that may be of some interest to the members here if you haven't visited there yet. The link is https://diyvacuumtubes.com/ It's somewhat dormant right now, but a lot of this old technology may resurface after they drop "The Big One"!
