In 1968 Sony sold a solid state small television. The pictures bring back memories.

i started working with tubes in the 1950s. i still love them and work with them every day

In WWII they had the proximity (artillery) fuse, which had fairly small, EXTREMELY rugged tubes. They all had to function after being shot out of an artillery piece.

Vacuum tubes were reliable, but they generated a lot of heat and consumed a great deal of energy. Instead of relying on massive cooling systems in their data centers, Big Tech companies should require microchip manufacturers to reverse-engineer vacuum tubes. It wouldn't be a bad idea to develop a new technology that allows microchips to be mounted on cooled vacuum tubes, as micro-level cooling management would reduce energy consumption in data centers.

RF transmitters only use vacuum tubes. Output tubes handle 25 thousand watts.

Current flows from negative to positive. Check how electroplating works. Negative to positive. Vacuum tubes, cathode is negative plate is positive.

When it comes to handling a lot of RF power, I still prefer a tube in amplifier circuits (4CX250B and 3-500Z, etc.). In my opinion, they are more forgiving than solid-state devices.

Well...look at all the high end audio amps which are 300B based the red Chinese are selling. I still think the 2AE's the best tube for any audio application but that's just my experience

And yet modern electronics is lying about the direction of current flow. The vacuum tube proved that electrons flow from negative to positive. Conventional current is used because of the flimsy excuse that the math works either way.

Talking about transistors all the time... poor video document.
