Selling: Gen 2 DEP XX1440 tube, the one used in the Kite Price reduced!

[pizzigri]

Well, I need funding for thermal, so all my project stuff needs to go. I got addicted to IR and most probably will only keep a PVS14...
So lessee what we have here.

This is a DEP XX1440 tube, it would be roughly an equivalent for good old EEV P8306C (however made years later, I believe), it's basically the tube that went inside the Pilkington Kite, and I believe also the L6A1 british NV.
It is a 18mm fiber optic output inverting image intensifier tube, powered by 3,7V (but it powers up just fine with 3V), has a S25 fiber optic PC input window and although used, is in great condition.
Perfectly working, very clear and with almost no blemishes, gain is excellent and image is good. Comparing with my MX9916 reference tube, which is a 28-30 lp/mm and has a 280 uA/lm PC, i'd say this tube should be at least a 32-36 lp/mm and sensibility should be around 320 or more. No snow, scintillation, or other hints that the tube will go bad or to air.
May have a very, very faint ghost image of the "V" reticle that was used in the Kite, visible only in very bright conditions (actually, I personally like it...). It draws very little current, indication of excellent heath of the power supply. As you all know, these tubes are quite "fat", but can be dremeled and split open, inside the boot there is a lot of potting and then it has the same diameter of a standard MX9916 form factor (at least a10mm longer though), and then can be used in almost every commercial housing out there.
Images of the actual tube upon request - I dont have a housing to test it, but I can fire it up and place it over a business card to show it works.
Sold as is, though!
I'd like to get 180 £ shipped - price reduced!

Updated to add pictures of the actual tube for sale.




The next image is the tube in low light with the PC placed directly (on contact) over a business card. I took the image with a Nikon D3S at 8000 Iso in a semi darkened room with only a trickle of light coming from a curtained window, and considering that the CCD inside the D3S is one of the absolutely best photo sensors out there, I'd say the gain of the tube is good.



This is an image of the screen in a completely darkened room (same settings as above for the camera) of the image over a white background. There's a ghost image of the Kite reticle, I used a sharpen more in PS to make it more visible, but it is really noticeable only in high light and over solid background. I could not see my hand holding the battery.
Very clear image, no blemishes!

Hi mate, the EEV tube you mentioned. That is what I am using at the minute, as I believe that it is gen 3. Do you think that this would perform less well than that one?

Hi, do you still have it?? Will it fit in a pvs5?? Thanks!!

Unlikely, given that it's almost 8 years since the previous post !!

By the way, I'm a newbie here, and also in night vision, so excuse me if this answer has to be in another topic. The thing is, I've bought a pvs5 for 30€, the seller hasn't sent them yet, but for that price I had to buy them, you don't see those very often here in Europe.
The device doesn't work, so I put myself in the worst case scenario where the tubes are fried, and I was looking for tubes that could work with this device.
I've been looking for MX9916, XX1440 and XX1410 tubes, but I've found nothing that non working US restricted MX9916 and the one in this post.
Do you (or someone) know russian/chinese/whatever gen 2 tube that can be fitted in the device and that is affordable?? Just want the device to walk in the woods and see the forest in the night.

Thanks in advance.

You may get a response but almost everyone on this forum who uses night vision is using digital night vision.
Tubed night vision is not particularly well regarded or sought after in the UK.
