Howdy all,
I'm a scientific glassblower (25 years now), and I make my own tubes.
I'm at www.incandescentsculpture.com; not much tube info there yet -been a few years in beta mode on them, but some other high-vacuum delights are to be seen. (My handmade incandescent bulbs, my Tesla wireless brush bulbs, the 'fuxie' tube....)
Even the production of a simple, low-mu triode is non-trivial; the requisite equipment and knowledge take years to acquire, and a page long essay to even enumerate.
OP, I'd be glad to help; perhaps we can compose a FAQ and parts list for kindred spirits.
