@crnazvijezda Anode is the upper cap, cathode bottom pins 1,4,6 or 9, they're all interconnected so it doesn't depend on which will you use. It won't hurt if you'd just short them all with a wire for this setup.
already saw it that was the first video i saw love the glow, but perhaps if there was less glow it would indicate that more xray was being produced maybe the real good ones dont glow as much ( wasted energy)
why was it making blue light? was this just the electrons bombarding the spattered material on the tube walls? I hit this spare old lamp I had with 60kv and it made a greenish yellow glow reminded me of crooks tube I think this was the krypton gas or maybe phosphorescent material, I was trying to make a small plasma ball but I guess it was the wrong bulb type or maybe I was doing something wrong, have no idea how they make those light bulbs glow blue n purple like a miniature plasma ball?
@ARCSTREAMS Depends on the tube and the vacuum level. To say the least, these tubes are small and this particular piece was NOS, so at this forward-mode configuration it emits lesser amounts of radiation and also it glows like a neon lamp, except with a blue glow, might be corona on the walls.
I should have an another video of the DY86 tube here; be sure to check it, did a real measurement there, also did a reverse-polarity setup (sparks were crawling along the tube)
I was googling x ray tubes and its very interesting stuff they show similar rec tubes like you got, seems they work on materials such as cooper, tungsten,molybdenum, palladium and rhodium witch I think is radioactive, what bombardment material does your tube have? it say only about 1% of the energy is converted to x rays but still your tube can be hazardous and may even be able to take pics if ran at 60kv, just a matter of hitting the right wavelength.
@Swedishpersondude Yes, you see the light on the intensifier screens, however harder x-rays (with higher energy) penetrate the plastic screen like a hot knife through butter ;) So yes, you would be still exposed to radiation.
And believe me, you need copious amounts of x-rays to light up a screen in real-time.
@ImJustSlime Do you have even a slight sense how much x-ray radiation does the DY86 emit? Well if you did, you wouldn't spit out such a foolish sentence like this.
These small high voltage rectifiers don't contain any gases at all. The reason why it shines blue is due to too high voltage applied in the forward direction.
Mercury vapor tubes are completely different; they were used to rectify huge currents - tens of amperes - before silicon diods became available.
btw yes, basically vacuum tubes emit certain numbers of x-ray when very high voltage is applied to it :3
may I ask, does mercury vapour tubes have the same type of getter? I can't stop wondering while getter is supposed to reduce the amount of gas in tube, how comes mercury vapor can co-exist inside the tube?
sorry if my english bad, it's not my native language :P and just started into tube amp lately, youtube got alot of interesting videos^^
Very nice!
Would you be so kind and tell me which pins are you used for anode and katode?

sound like your radioactive detector in the background was really clicking away

@ARCSTREAMS Haha, that's nothing. Check my x-ray tube or 6VS-1 video, in there it chirps like an AM radio.

well every tube does that a little bit.

Check my other x-ray videos, folks."X-ray First tests", i.e. - there's a real xray tube.

@Swedishpersondude thanks captain obvious :)
However, you are only half right. You can convert high levels of radiation to light with x-ray intensifier screens, i.e. in fluoroscopes.

@TheReal1inflater
Well if u do that ur looking at light and not Xrays, right ? xD
Since u convert Xray radiation into light ;o
Btw cool little thing u got there

that's mercury vapour glow usually found in rectifier tubes
