- This video comes from Tesla company archives and was presented on exhibition called "(Un)forgotten Tesla" in Valasske Muzeum v Prirode in town Roznov pod Radhostem - town where Tesla originated from.
I would like to thank to Valasske Muzeum v Prirode for making the video and for keeping it for future generations.

Thanks for posting this I love old electronics documentaries (especially from the 1970s and 1980s) AND stuff from "behind the iron curtain" so this is an excellent addition to both collections. :)
At 1:00, those are induction coils coming down over the tubes to hit them with high intensity radio waves or microwaves briefly, to heat the elements red-hot for a few seconds, so that contaminants will be cooked out of the elements and the getters (shiny metal spots on the glass) can chemically react with and neutralize the contaminants, ensuring a clean, non-conductive vacuum.
Thanks for the insight
weird flex but okay
@@testpipedh22a , of course its a "weird" flex, because it wasnt meant to be one. It's factual information, which can be difficult to find relative to tube manufacturing, and the purpose of those coils might not be apparent to the average viewer. Besides, there is lots of confusion about the Getters inside the tubes, and how they got there, and what is their purpose. Some people such as myself enjoy seeing things being made, and have a mindset bent towards science and engineering . If, in today's social environment, trying to clear up a possible question in people's minds constitutes a "Flex," some kind of a boast simply for sharing factual and historical information, then I don't know what to say about that, other than "sad"....
Yeah dude I actually appreciated your comment, I was just kidding. Thanks for sharing!
cool info, thanks.
Vacuum tube technology is amazing....
Thats why old vacuum tubes are more expensive.
I have made an audio amplifier with 6e2 and 6p1 tubes, used from old radio, and the output sound is perfect.
I really like it, but the audio contains a lot of wow and flutter. It has probably been recorded from an old cassette player/magnetophone with bad capacitors.
Seeing her hold the CRT by its neck made my heart stop.
Me too
Great historic video, thanks from England
To byli časy 😊
Good video for archive purpose. It's great to see actual people working with their hands instead of all this computer automation.
BUT WHY IF MACHINES CAN DO MANUAL LABOR LET EM
@@russianvideovlogguy ...... I rather see people with jobs and also learn . Besides, people buy tubes, machines don't. Have a good day and stay safe.
Makes no sense to me.. So should we stop using heavy farming machinery and go harvest fields manually?
Ótimo vídeo congratulações
The wonderful era of Electronics...
You can see the CZ was advanced. Automated plant, corrugated shipping boxes and styrofoam dunnage.
bons tempos aqueles, eu aprendi eletronica naqueles tempos.... deveria voltar....
Cool video. It's a pity that the sound is so distorted.
Must be caused by a faulty valve.
That is normal. A lot off videos made in czechoslovakia in that era had this bad audio except for normal films.
@@tenpotkan7051 Maybe the whole of Czechoslovakia was involved in a Fallout 3 Vault 92 style white noise experiment LOL You never know. I mean I can't think why a country couldn't have clear audio in that era.
@@boredfartless4221 It was because of low quality of sound equipment. Having advanced audio technology for commercial and public use wasn't really something perceived as necessary by the socialist government. Besides that, educational films weren't supposed to bring audible pleasure, they only needed to have sufficient understandability. Combine that with a background music played on a wobbly vinil record and a speech sensed with metal diaphragm microphones and you will get this video's audio.
@@boredfartless4221 "White Noise Experiment" lol... would be a good name for a thrash metal band.
Bettet learn vacuum tubes now- because after potential apocalypse transistors would be impossible to produce, but the vacuum tubes would be easier task...
Wonder what the life expectancy of the workers was?
Why?
Workers are young because people move on to better jobs not because they die.
The good old day's, no covid or global warming 🤔
So old vacuum tubes are so expensive because they are made by mostly hot grandma's!!
ايام خير وبركه
This has such an old Soviet Creepyness to it
whoa so cool
Dejte sem originál bez toho šíleného "odšumnění", nedá se to poslouchat.
Toto je jak jsem to dostal..
💯
i see the video , i think Why WE300B have good sound ?? maybe pretty girl HAND MAKE ,,
ГУ50 at 1:24
No, GU50 is a pentode and the tube at 1:24 is a beam tetrode.
+ Zaprodk- I can't undertsnd it anyway. 😏
Я знал что коронавирус был уже давно! 3:50
Не против, есть чему научиться. Но, работают, многие наши граждане- не думаю что это хорошо! Могу ошибаться, скуден умом.
I hope tube production restarts here!
