TVN-2T Night Vision Periscope

Hey Jow Forums,

I got my hands on a TVN-2T. Took it apart, seemed like it was in good condition.
In the process of figuring out how it works and how to get it powered, now.

Here's a similar model. On the left is the power cord, which mine doesn't have. Trying to figure out what I can do to power it. From what I read, it needs ~22-29 V.

Are these meant to be mounted in armored vehicles?

Here's how I believe it's wired, cord plugs in on the left, from there it's (seemingly) a single wire which branches off into each tube.
Tried to disassemble the tubes but didn't want to possible destroy anything so I've stopped for now.

Yeah, I believe it was initially used in T-55s (as per optics-nj.cz/en/tanks.html, still in the midst of research).
Apparently this one was taken from a BMP during the First Gulf War.

Let echt fucking op met het voltage man, minder dan een volt te hoog voordat deze de transformator ingaat en je hebt de buizen doorgebrand.

Deze nachtkijker heeft geen gedeelde componenten met de PNV-57, en loopt ook niet op simpele batterijen. Raad aan om naar duitse onderhoudsdocumentatie van de NVA te gaan zoeken.

I don't know Russian and my knowledge of the Soviet-Afghan war is scant, but:

Tag appears to read "Attention! Kokchil work shop close" (Google translate)
Still looking into Kokchil, but I found mines.pajhwok.com/news/mineral-resources-badghis-province which says it's an area in Afghanistan, my guess is it was brought in during the war, then sold to the US for the Gulf War.

Not Dutch, but I really appreciate the info.

Would there be any visible signs if the tubes get burned?
For powering it, I was thinking of looking into getting a hold of a variable machine and hooking that up. Not entirely sure how to wire it, it looks like there's only 1 wire in the whole thing.

I'll check out NVA documentation, that's an interesting lead. How come they'd have documentation on it?

They essentially either start fading white or black when they burn out. I do advise covering the lenses of the thing whenever the assembly is exposed to light. Some tubes burn out when sunlight or lamp light shines in to them, even when powered off.

>I'll check out NVA documentation, that's an interesting lead. How come they'd have documentation on it?
They don't, their manuals should just be translated from russian. It's because german is a language commonly taught, or easily understandable for a person that only speaks english with relative ease. Have fun reading the russian manuals if you don't know a word of russian, and in this specific case, technical russian. Trust me, knowing technical russian is quite a feat, even when you're a native russian speaker.

>For powering it, I was thinking of looking into getting a hold of a variable machine and hooking that up. Not entirely sure how to wire it, it looks like there's only 1 wire in the whole thing.
I think you mean one wire with 2 smaller wires packed into it, otherwise the ground contact would have to be made to the vehicle chassis.

I have no experience with soviet vehicle electronic systems and what voltages they run at. One thing is clear though, they don't run on typical western voltages most of the time, although you can sometimes get away with running a western 9v battery in a soviet appliance that needs a 12v battery.

it actually says: "Finished working - close the shutter"
