  1. Absolutely fascinating video! Who knows, maybe some of the tubes shown were the 2A3's and 300B's that reach astronomical prices on audiophile markets today? To see all those people working on the machines... Makes me appreciate their work even more - given that a lot of them was constantly exposed to heat, hazardous materials (barium etc.) or asbestos, which wasn't known for its carcinogenic properties yet. I bet OSHA would have the place shut down for good if those were the modern times. Modern plants like JJ, Svetlana and probably some others operate at much smaller scales now, given that they vastly limited the range of tubes they offer. Anyway, I'd love to make vacuum tubes on a lab scale, but getting my hands on the materials and equipment is near impossible...3
