At the university in our lab we built very complicated vacuum devices, basically huge vacuum tubes with very complex internal structures, including those providing motion. The metal structures we built by hand, using spot welder, cutting sheet metal with scissors. These would then be delivered to our team of glass blowers, the true miracle workers, who would put it all in fancy shape glass envelopes.
The next step was taking it to the vacuum stations where mechanical and diffusion pumps would be working for days before reaching the proper vacuum. During that time the metal structures would be heated to de-gas them and the cathodes would be activated.
Finally it would be delivered to our labs, where hundreds of wires would be connected to it for the studies.
The vacuum tube production areas of Svetlana and other factories (that I have visited) are not what most people expect - there are no clean rooms there, the whole environment is more akin to a machine shop - oil soaked asphalt floors, poor lighting, crowded and not too organized, a lot of manual labor.
It is truly amazing that they still produce devices that work. :)
