anyone ever done a diy setup with these there rather big and large field of view

on the net says there between 10-14k operational voltage and the focus runs 500v

I have a few power supplys for gen1 but there higher voltage except one I have coming which is definatly 14k but only time will tell if it works

I have two new old stock tubes and I want to do something with them
Link Posted: 12/11/2014 5:32:27 AM EST
They are Gen1 - Fun for a project, but lack gain for anything serious -

They might make a fun project, but you'll need a suitable power supply.

Don't go over 15000v or you might start producing x-rays -

X-rays as in see bones or x-rays as in I can see what's under women's clothing?

ok yeah I got a 14K power supply

how does the electronic focus work?

This was the tube i based one of my early builds (1994) on too long ago cant even remember what happened to it. Tube and psu were from Oatley electronics in Sydney. Abex sell a lens for these tubes think they were taken from a vehicle of some description. I have been trying to dig up a suitable psu for the tube as I have located another tube NOS and purchased a lens from Abex (UK) cant for the life of me find the old circuit diagram for the psu I used earlier. I wanted to get it going as it would be the only single stage gen1 tube I have and would fit in with my other NV scope well.

cheers

apparently the focus is done via a pot switch so u turn the dial up and down raise the voltage or lower it to adjust the focus
Link Posted: 12/21/2014 6:12:33 AM EST
ok ive brought a big scope with a 60mm objective lense in the test to see if I can fit this tube into the objective lense side with some work and I have a power supply to power the tube but not the focus adjustment
Link Posted: 12/24/2014 12:46:21 AM EST
so I brought a Chinese zos 10-40x60 scope and the tube will fit into the objective side and the lens will fit into the sun shade threads is the same



so this could be workable

As crazy as I think this project it, I really really want to see how it comes out - :)

Good luck with it - Please post pics when you get it running -

What state are you in? If you're in WA, I can probably find you a spare Gen1 tube and PSU to make it if you have issues with the PSU -

Regards
David

im in Victoria ive had a test on the optics of the scope its very good don't know if the optics are compatable with the tube but only one way to see

even if the poject fails the scope will see some use
Link Posted: 12/24/2014 7:18:56 PM EST
ive got multiple psu's for various gen 1 scopes and gen-0

just found ones that will work to suit a ww2 gen-0 tabby type e

they need to be the right voltage though modern gen 1 is 18kv tabbys 3-6kv older gen 1 can be anything from 12-14kv

Once they get up towards 20k, best to keep a geiger counter handy - Tubes will emit x-rays somewhere around 25K, but some are produced at lower levels ( was a problem with a lot of Russian Gen1 ) and I'm not sure where the safety limits are -

Most x-ray protection circuits cut in at 15k.

ive heard that

infrared is radiation there is many kinds of radiation light, microwaves and xray

but there ment to have lead glass on gen 1 tubes

so far most gen 1 stuff I have owned I can see just as good with my eyes in cloudy low light levels but its good in half to full moon


these tubes are very big so id say they would do better then a standard tube
Link Posted: 12/26/2014 6:28:30 AM EST
well I put a 12kv psu on it and they work but seems like its not enough power as only half the fluorescent screen lights up
I have a Yukon power supply here too but don't know how to test the voltage it has a adjuster on it though
Link Posted: 12/26/2014 9:17:47 AM EST
should be 18 kV.

Yukon usually use Ekran EP-33 tubes in their gen1 devices.

whats there new tube that's not fished eyed or did they just used better lense's

it is EP33SF-U,with convex photocathode,somewhat improved resolution and distortion,but still EP-33.

http://www.ekran-os.ru/ep33sfeng

they call it "CF-super" technology.
Link Posted: 12/29/2014 7:13:55 AM EST
has anyone ever found a supplier of these tube ekran never replys to emails

I found a source for ekran in china but I got one tube was ok but bright dot in centre and rest seemed dull

back on track I found I could up the voltage on the 12k powersupply but with out focus or the correct voltage I don't think the tubes will work
the screens only lighting up about half and its out of focus with no lenses but could identify a window fram just

anyone got a idea were I can get a PSU

I have the PSU from my now defunct T3C-2. The PSU works fine and it is designed for a Russian Gen0 tube exactly like the Ekran you provided the link to.

beware,if you are using FireFox - this site makes my FireFox to crash every time i open it. :D

good luck!
