Submission + - Ask Slashdot - Need Help In Making My Own Vacuum Tubes 2
mallyn writes: I hope this is appropriate for a geek forum. I want to try to make my own vacuum tubes. Is there anyone here who has tried DIY vacuum tubes (or valves to you Europeans)? I need help getting started (how to put together the vacuum plumbing system; how to make a glass lathe; what metals to use for the elements (grid, plate, etc). If this is not the correct forum, can anyone please gently push (shove) me into the correct direction? It needs to be on-line as my physical location (Bellingham, Washington) is too far away from the university labs where this type of work is likely to be done.
