Mercury vapor rectifier tube
Ғылым және технология
This is a full wave mercury rectifier tube type "1738" from the 40s, it is a low voltage high current type (15 A, 90 V max.) intended for battery charging, etc. E40 Edison screw socket. Video shows operation at half and full wave. The light produced by the rectifier is quite intense.

dude that tube is awsome
How cool is this. What a great find!
What a gem of a find!
Nice tube. Thanks for sharing this.
The main drawback is that you have filmed it with a 30 fps camera while the valve is powered at 50 Hz, so, the unavoidable flickering of the image.

indeed, perhaps the newer iphones or whatever smartphones with the higher frame rate recording option could be useful

Actually if the phone were set to 25 hz you wouldn’t see the flicker…

ElectroBOOM's favourite thing before selenium blocks :D
Hah, Tesla tube and Edison socket. What a great combo.

Nice! I have two similar looking tubes that are apparently rated for... 10kV and 1.5A?
I can see the deathray come out of this thing!!
Nice, thumbs up :)
Love it
That baby is putting out some big time UV.

This one is pretty low voltage (used in a lead battery charger).. might not be as bad as it looks

Nice
How mich voltage?
Very cool. Or is it hot?
Good morning. Yes !!! I would like to know, if it does not contain mercury, to provide a bluish light? Is it non-toxic mercury? Are these sources still made? THANKS
So incredibly cool. Wow. What is the expected lifespan of this beautiful beast? Hours of operation?

Should be somewhere around 1000 hours, depends on load conditions and number of on/off cycles... However, the large (usually multi-anode) cold-cathode mercury arc rectifiers can go into tens of thousands. I have a video of that as well.
Is it contain red mercury
It was even made by Tesla! Pretty much the original electrical company by Elisa Tesla himself and not the modern electric car company! :)
wow
I hope you wore UV filtered eye protection...
What are the wires you disconnect part way thru?

I connect the second anode.
Tesla! JJ! I love this company! RFT and LAMINA - also!
What kind of forward voltage does a tube like that have? I’d imagine if you’re rectifying 90V, you would be losing 50 of them to create that aggressive plasma. Could be totally wrong though.

Its not that bad, if I remember correctly the drop is around 15V...

@@jmartis2 Thanks for the answer! I knew mercury vapor was good at generating plasma but I’m still impressed that it can conduct at that low of voltage!
Now you're Australian.
Love it tesla 1738 is the best
jojo Tesla to je hodně kvalitní sám je používám :)

popraw a why do people always think this were is the 50kv? were is the extremely high vacuum jmartis2 it is save to look into i do it all the time with my mercury vapor tubes and i never had welding eyes
Tesla in 1990 making Mercury Arc Rectifier.
