- Vacuum Tube Electron Theory and the Diode: An Excellent 1942 Training Film gives clear explanations of how various vacuum tubes work and how they are used in electronic devices. Produced by the U.S. Signal Corps. Film # 1-140. Run time: 15 mins.
Electronics
Valves
Signal Generators
Schematics
Diodes
Probably the two most important inventions of the 20th century was the vacuum tube (Thermonic valve) in 1906 which led to modern electronics like radio, television, radar and the earliest electronic computers. Then in 1947 the transistors which led to the amazing technology we have today. The diode tube invented in 1903.
Great video. The latest technology. Just later than usual!
And that is how the electron do.
Videolabguy, agreed! & Interesting how many of the 1940's and 1950's tubes are still available on eBay, and still test strong! - Victor
vacuum tubes are so fascinating to me !
Thanks, Rachel. Glad you enjoyed it. ~ Victor, CHAP
Still used today in state of the Art HiFi systems
Straight back to basics. I love it.
I always wondered why those transformers with multiple output taps were so common when I was learning electronic hardware. That second winding was for the heater. I never worked with tubes because I grew up in the 80s but those transformers were pretty common.
People had much smoother voices in those days than now.
Best paid voice actors for sure.
Both diodes in the rectifier example are backwards for the polarity of the shown waveforms.
It is correct in the transformer circuit.
Like from Brazil.
In childhood we seeing back side of valves radio where are the men who sitting in the tube and taking what was carege of radio..
Tube technology still used today
oscilloscope history pls.
A good suggestion, thank you! ~
So why Dec. 7, 1941 they used normal telegram to inform Pearl Harbor about airride if they got so well equipped Signal Corps?
From tubes to microchip
hot Radium anode?

What i learn from this long explanation:
the disappointed face
Hadn't noticed that face. Good spotting! ~
Can't you upload them in the original aspect ratio? Ironically, this vid doesn't look good on a 4:3 crt. Still, Thanks for this :)
All films were 4:3 until the 1950's. During the 1950's Cinemascope was invented which stretched the image from 35 mm film into wide screen then 70 mm film was developed around 1960 which gave true wide screen image with wider aspect ratio.
Tube radio sets were more easier to repair
Wow this is so krass
