Those tubes are basically just like massive diodes made to handle ridiculous high voltages without biting it. So, it's outputting a clean DC signal all the time, and i think the tubes also help to even the voltage out further by being slightly capacitive in nature.
Very nice indeed. We've got a box full of those tubes We powered one up and the geiger counter went nuts. We also kept the 150kv transformers. Great fun when you're bored at the weekend :-)
When tube rectifiers get old, they get "hard" and can drop voltage across them, and can and will emit xrays out of the tank it self, worked on many, when you have hV across them...that's why way back, the mfg came out with solid state rectifiers that screwed right into where the tubes where...did many up dates, now the only vacuum tube is the xray tube, no solid state for that, cus...ya need vacuum, and hV and an anode the acceleration gives ya xrays
those tube look a lot like a Kenotron, a high voltage high vacuum diode. they were commonly used in x-ray equipment. sadly i could not find the data sheet yet, but i will keep on looking.
Yeah, these kinds of rectifiers make great controllers for HV. I can't tell but they are tied together as a 2 half ~ or a full wave combination. This is what turns the AC to DC. Maybe two by two in parallel since this transformer is so massive. Most of tubes this size are rated for 100kv or so. I have one rated for 125kv, which is the highest rating I have seen. It's huge, twice as wide! I would be very careful with this transformer as it must be in oil and since it's a 60hz, it's VERY deadly.
Sans oil and metal housing, what does that thing weigh? I'd love to get my hands on one of those, but it's well outside of what I could handle.Too heavy and, knowing my luck, I'd end up with 5 gallons of PCBs to dispose of.
Hi Chris, id love to share a cool article on wikipedia with you regarding thoriated valves and the types of filament they use but youtube won't let me post the link in the comments.. your probably gonna be able to find it real easy via google but if not drop me a pm on here and i will send you the link.
Why rebuild what was already built? You already had a HV power supply with the bridge rectifier, just put the tubes back in and reseal the transformer case back up and done. Otherwise you could sell the tube on ebay and the transformer as scrap and turn a profit.
Mute it at 6:52 and play some dramatic music in the background instead for about a minute :P You're welcome :D You remind me of Dexter in those black gloves (What do you mean, "Who?"?!) Keep up the very excellent work!
TUBELOVE! Hmm. I can't seem to find any data sheets for those tubes. :( This is about all I could find: pupman.com/listarchives/2001/February/msg00175.html The problem with using them in a full-wave bridge,is that each tube will need it's own filament supply,isolated for howevermany-KV you plan on running it at. More oil!
Those tubes are amazing, I look forward to seeing the finished rectifier glowing under full power :D
Oh wow, God rest you fella. Still affecting our own lives after you're gone, the world is poorer without you.
@@danmackintosh6325 I agree seeing his comments upsets me. He’s was such a awesome chap. Bless him. Looking forwards to seeing him again some day ✝️🙏😇

Remember that high voltage diodes will emit some x-rays when in use, so don't stand right over them looking at the pretty blue glow for very long.
If a third of the people in the US operated on this level of knowledge, we wouldn't be worrying about economics anywhere near as much right now.

That motor thing switches the federal ports from
radiography to fluoroscopy mode.

Watch again, and listen. He even names the brand and type.
Nice jobs, sir
with those tubes you can make x-rays as well...
thoriated tungsten electrode vac tubes!!! you sir are a lucky man
Industrial x-ray can go up to 300Kv. it requires a big ass connector and a cable as thick as your wrist.
Thank you! We agree, tell your friends. ;)
You REALLY deserve more views, great videos :-)
excellent !
He's on the WEST side of the Atlantic Ocean, bellend.
We use to have similar tubes to those for controlling the bias, via a rheostat, on saturable reactors used for stage lighting dimmers.
Pretty amazing peice of technology. Amazingly dangerous too.
VR-17C is a Voltage Regulator Tube

Just courios; what would be the lowest voltage that this tube can rectify? And how may amps? Do You know that?
But a-node and silenoid are not the typical american pronunciation, either.

Is "batman" a paid employee ?
Ayynode, silenoid? WTF is this guy on?
have you worked on any Gulmay-UK x-ray transformers?

who is the manufacturer of that rectification tubes??
Wow so that transformer would pull 100W just for filament heating of the rectifier tubes! lol :D

What sort of oil was it filled with!? o.o
it would be sweet to come and build it but i have no goddamn idea what to do with HV stuff xD

I am a manufacturer of such transformers here we give portable tube heads and many more .. want to know more let me know.. TC
240 is two phase not single phase
Any chance of building a guitar amp using those tubes?
sunburstbasser no, cause these ones are for voltages above the 1kV range
Hook it up for ac then see what 110 gives you
All vacuum tube filaments are thoriated tungsten, so they emit ELECTRONS!
Too bad this place went out of business
The next chapter is about to begin. ;)
A few hundred pounds. :)
