Wow..this stuff is a lot to learn. I am sure the Russians still use vacuum tubes in their planes or secure systems since supposedly an EMP nuclear warhead will not affect them. Any truth to that?

always good to have them. I was talking to a HAM radio operator while doing my UPS deliveries. During the floods in Calgary, the army was called out and local ham operators used their vacuum tubed home sets to communicate. Whether it is the 'zombie apocalypse LOL' or a natural disaster. Keeping old school technology is the way to survive, for the short term, the disaster at hand.

There are plenty of us left who still know how they work. They're still used at sea in radar systems.
