I'm curious if anybody knows why Russia is a leading tube manufacturing country? The history of why? I found this chart of old and new tube symbols. Though it might spark some interest. www.ominous-valve.com/russtube.html

When the USA and most of it's allies were phasing out their use of vacuum tubes during the Cold War era the USSR's military was still largely based on tube technology. Remember that the USSR's economy was centered around supporting their military; one of the main reasons it failed. Consequently, when the Cold War finally ended in the early '90's Russia still had plants manufacturing tubes while those types of factories in the USA had closed. Also, EPA regulations in the USA have made tube production costs prohibitive while Russian manufacturers aren't faced with those limits. After the Cold War Russia was looking to export anything they could to boost their ailing economy even though the world market for vacuum tubes was relatively small.

This is interesting. I wonder why the Cold War era? I'm guessing everyone was afraid that a nuclear attack would take out a power main?

Technology was just evolving and it evolved faster for consumer goods in the West.

One reason that tubes were still preferred in aircraft technology in Russia was reliability- really. As I understand it, Russia had apparently devised a way to mount tubes to handle G forces better than the fledgling silicon systems and they were thought to be more impervious to radioactivity.

Too bad the aircrews weren't impervious to radioactivity.
