Cool topic.

Since I just had mine apart for cleaning I snapped a few crappy cell phone pics.


Tube Info:

K&M 272864-8
S/N 962375DC0549


Great image and near flawless tube. One small spot on the near edge of the image which I thought was internal dirt but apparently not the case.
Manual gain control and single AA battery power.

The point of this thread is for us all to learn. If I simply tell you what you have nobody will learn anything. Give us details ! Does the tube whine when powered up, does it have a date code ? We will add to the details as time goes on. I will say KM is owned by ITT so with minor exceptions we know it is a ITT tube. I also can say KM on the tube means it is older. Give or take around 2006/2007 ITT stopped using KM and switched over to ITT on the power supply .

As time goes on we can nail this switchover date down ! Even I don't know the exact date.

ETA: Try a Google search of the power supply number

Nice pics of a very early MX-11769 Litton tube ! Thank you.

Can anyone add more details on this power supply ITT K&M 272864-8 ?

ITT patent for the PVS-14 and the MX-11769 tube it uses with variable gain. Also the ITT patent for the PVS-14 lower housing circuit board. From this information we can see the PVS-14 and the MX-11769 tube came out around the year 2000 give or take. The tube and housing were designed around the same time to work together.

https://www.google.co.in/patents/US5943174 PVS-14 housing.

https://www.google.com/patents/US6288386 PVS-14 lower housing.

http://www.google.com/patents/US6150650 Patent from ITT and KM for the MX-11769 tube with variable gain.

No audible sound or whine of the tube when powered on or running.
I swapped the battery housing from the two AA battery housing to the singe AA battery housing.

The serial number S/N 962375DC0549 lends a clue



I think the date code breaks down DC / 05 is the year 2005 & the 49 is the 49th week of that year ?

OMNI - IV / V spec range ??

Yep, Omni IV to V range and not gated. This was also known as a SELA tube. Basically a civvy Pinnacle before they let us common folk have autogated tubes. ITT F9815 tube. These tend to be real nice thin film tubes that just did not get autogated power supply's. I have added your tube info to the list ! Thank you.

You're welcome ! You and a few others really hammered me to do this. I will keep a running update in the first post. We will never get to know EVERY tube but we can figure out most of them.

Nice ! I have never seen a autogated tube in a Envis scope so I have learned something. This is a Anvis or aviation tube. It has a metal casing where as most tubes have a plastic casing. The metal is for EMP shielding and is a Air Force requirement.

Envis scopes usually have tubes that failed milspec for minor reasons such as blemishes. They are usually nice tubes ! So we have a date code of the 33rd week of 2009. Anyone want to take a stab at it ? We have no pigtail here so we know it must be a MX-10160 tube, MX-11769 tubes have a pigtail for variable gain while MX-10160 tubes do not. Both tubes use the same tube module but have different power supplies.
Link Posted: 6/22/2014 9:42:07 PM EDT
Notice the different looking pigtails for ITT and L3 (Litton) tubes. They are vastly different and is a easy tell as to who made your tube. You have to be careful though as we have proven that sometimes power supplies are sold to competing manufacturers. I have only seen this on milspec tubes but who knows !

Thank you very much for your help. I purchased this envis unit off ee here.

I found a tube on ebay with same ITT number and it is advertised as "ANVIS MX-10160C F9800 Thin Filmed Autogated OMNI VII Image Intensifier Tube". Is all of it true?

Bingo!! You solved your own tube ! It is indeed a MX-10160C ITT autogated tube. I will add your tube to our database !

Because it is not a milspec tube and has no data sheet we have to estimate specs based on the date of tube manufacture. I would put it at Omni VI to VII performance leaning more to Omni VII

Wonderful. Previous owner said it passed Hoffman Testing at NVDepot and under 10 hrs of life. I've never heard if thid test. What's my tube worth brand new? Would you mind adding value in your database? Or would that de-rail your intendions and/or this thread? Once again thanks for your help?

I don't want to add tube value to this thread as it is not about that. I will help in this one instance. All other tube values can be handled by PM. First off it is a used tube with no warranty. If it blows up in the morning a used buyer is stuck with it. New this tube is over 2K. I would put a used value of $1200 to $1500 dollars. Really depends on interest at the time of sale. If you get two guys bidding who really want it who knows. I have seen tubes I would classify as beater tubes go for ridiculous amounts.

A uneducated fool can be relieved of his money very easy. Good to have forums like these that educate !

ETA: I used to be one of those guys who relieved uneducated fools of their money. I learned about night vision from buying and selling used scopes. I would scrap broken scopes and sell the parts. I did this as a way to supplement my income. It was a hobby and I learned what makes scopes tick in the process. Anything I bought I took apart. Doing this I saw and learned about many scopes and tubes.

I don't do this as much as I used to but it was how I learned. I was a junkyard night vision guy. If you needed a part I had it. I still buy broken scopes that interest me to just see what is inside. I am a totally self taught night vision guy. I also had help from some old school guys who guided me. I made plenty of mistakes that cost me many dollars. The mistakes that burn your wallet help you learn. I got a lot of learning over the years !!

Envis tube does not have a pigtail because it is a MX-10160 tube without variable gain. Pics are right here in this thread. Look at the Litton M814-1201 tube pigtail. Then look at the very first tube pics in this thread which is a ITT tube. Remember, not all tubes have pigtails.

L3 or (Litton) power supply pigtail (This is not a factory L3 tube by the way)



ITT or KM power supply pigtail.



Look at the ends of the pigtail where it plugs into the lower circuit board.

I'll give it a whirl *crosses fingers*

filmless autogated Gen 3 made by L3
possibly for use in an AN/AVS-6 maybe omni 4-5?


I dont really know what kind of information I can get from the serial number, or a place to search for it. I googled it with no luck.

I'll give it a whirl *crosses fingers*

filmless autogated Gen 3 made by L3
possibly for use in an AN/AVS-6 maybe omni 4-5?


I dont really know what kind of information I can get from the serial number, or a place to search for it. I googled it with no luck.


You got it partially right. It is a L3 filmless MX-10160 tube (AKA Gen 4) It is not a milspec tube so technically Omni nothing. Performance wise it had a S/N of almost 34 so it blows away Omni VII or VIII specs. Filmless tubes can be some really high performers. I am just not a fan of them. I won't go into detail about filmless tubes as that would derail this thread.

Dino, you should do another thread on Tube damage types and what causes them, and even how to potentially minimize or fix them. I've seen lots of threads from users with light scars who freak out asking how to fix it.

Any value in trying to post a "thru the tube picture" to attempt to demonstrate the tube image along with its ID ?

While I know a good deal about this it falls more under the tube science division (CJ7Hawk). I think he would be best for that one. I will share some old SELA tube downgrade codes that were on the data cards. GZ=blown aluminum (spot), SZ=cathode trash (spot), OO=phosphor streak, EX=exhaust streak (don't really know what that is), ZP=spots, MA=MCP arc damage. ITT civvy tubes used to come with secret codes telling why they were rejected from milspec. This is not ALL the codes. I had one heck of a time getting the ones I have. Ask CJ if he wants to do a tube damage thread. I may have my hands full with this one !

From a Google search I find an old thread at another NVF. You may recognize some of the screen names talking about it. While these are not always accurate it all adds to us getting clues to identify a tube.

OK, let us do this tube. This is going to be harder. Still, we have clues ! (One of my tubes I sold a few years back) We have already learned it has a L3 power supply due to the pigtail design. We can assume it is a L3 MX-11769 tube but it does not look factory and is missing numbers. What is going on here ? These type of tubes are the absolute hardest to decipher. I bought this tube new for a comparison test I did awhile back. I know what it is but had it just came out of the blue I would have a VERY hard time telling you what it is.

I got close up shots of the pigtail because I want to see if the pigtail design looks different from L3 autogated tubes to L3 non gated or DC power supplies. This tube is not autogated.






I have already found out who designed and made the pigtail.

all I can get from that one is the cage code LENTHOR ENGINEERING INC and the date.
more hints?

ETA: my post was after your edit, I suspected they only made the pigtail since thats what their website said they do


ETA2: I searched the part number as well and i got nothing, along with the other number. I dunno where else to look for clues.


ETA3: wait could this be a blem B grade tube sold by TNVC? (I found an old thread about this tube)

ETA4: tube has been repotted and thats why there are no markings?
Link Posted: 6/23/2014 2:39:41 PM EDT
"Clean" tube with minimal markings = Export model or made for a discrete contract build ????

Ok, The tube is obviously devoid of markings but we know it is a L3 tube and power supply. As I said this was a tough one and I had a unfair advantage here because I bought it new. That said we still know this is not a factory L3 tube. Tube manufacturers like L3 and ITT always label their tubes. This is one of those secondary tube manufacturers I talked about.

This tube is a AEO tube. You can Google AEO and learn more about the company. AEO buys tube modules and pots them. They have also bought warranty returns and repotted tubes. Usually if a tube has a dodgy power supply it shows early on. This is why the major guys "burn" new tubes in for a number of hours. It weeds out defects before it gets to the customer (most of the time).

This tube was supposed to be weapons grade for a PVS-14. It had a DC (non gated) power supply and a large halo. Many dealers use AEO tubes for lower cost scopes. They can be great tubes and also lower quality. Just depends.

AEO also does tubes repairs for folks. They will repot tubes that have bad power supplies (expensive). Summit also tried their hand at potting tubes with mixed results. AEO has been around a long time and can put out quality tubes.

No way to tell specs here except from my own eye. I can't say what vendor sold the scope with this tube (was NOT TNVC) as it was sort of a covert tube inquiry mission. So now we know what a non factory tube looks like (they can look different in many ways though). But with clues we know it is L3 based and I know from experience who made it.

While we are waiting for guys to post pics of new tubes for us to decipher I have many of my own to keep things going. Next tube up is a milspec tube pictured next to my filmless L3 tube. Milspec tubes are easy and you guys got this one without my help. Tell me what you know about the milspec tube. What scope it goes in, who made it, gated or not ?

cage code shows its made by L3
tube is a MX-10130D+/UV
should be autogated
judging by contract date im gonna say Omni VI
looks like it goes into an AN-PVS7

judging by the warranty exp. I would say it was built under one of these two contracts
DAAB0702CJ00* - 05/03/2002
DAAB0702CJ01* - 05/03/2002

(not sure if im allowed to post contract's so I censored the last digit)


did i get close??!?

ETA: I saw the contract on the tube after I posted, tricky lighting!!

This should be spot on. It is an L3 Omni VI tube out of a PVS-7D
Link Posted: 6/24/2014 12:56:06 PM EDT
[Last Edit: 6/24/2014 2:52:29 PM EDT by Dino1130]
Contract numbers are public information so no issue with posting. You guys are spot on !! Omni VI autogated tube for a PVS-7. The PVS-7B and PVS-7D are the same body housing and because of that can contain many types of MX-10130 series tubes.

The MX-10130 series tubes are non inverting. MX-11769 and MX-10160 tubes are inverting. That is why they are slightly longer. They have a fiber optic twist that inverts the image. MX-10130 tubes being non inverting have a limited use. They are used in the PVS-7 and some rifle scopes. The MX-10160 is by far the most popular tube in the world. It is used in darn near everything.

The PVS-7 also has a interesting story. Kind of a fight between L3 and ITT. The MX-10130C tube was the first tube to be able to be used in all PVS-7 housing designs. Before that we had a MX-10130A and MX-10130B tube. L3 and ITT used to play around with the tube contacts so their tube could not be used in a competitors housing. I assume the Gov told them to knock it off and the MX-10130C tube magically appeared which was produced by both L3 and ITT.

All tubes starting with the MX-10130C and later used the same contact design. The PVS-7 also used Gen 2 tubes. The PVS-14 never used Gen 2 tubes at all.

I think this is an awesome thread - so I'm going to second that - And I'll add a little bit of information also -

One of the best sites for tracking down contractual information ( which is all public ) is NSN-NOW.COM - Sign up, and search... Through this site you can track down the contract and other details for most ex-Mil tubes. It's very effective and will show all the deliveries of the tube, and who by, which in conjunction with the date of first delivery, will tell you which Omnibus the tube is from.

One thing about Gen3 tubes also, is from time to time I find a tube that looks like a Gen3, but is actually a Gen2. It is possible to tell them apart visually, but only by reflection. A Gen2 Photocathode, in blue, behind glass, will reflect with a pattern of many images, mostly a light red, as well as a single primary reflection. A Gen3 will give two reflections of almost identical size, one white/yellow and the other light-blue.


I'm off for a few days but when I come back, I'll add some further information.

David.

I'm gonna Google image some tubes this evening (hopefully) and see what we can find to play with.

How about this one:

Anvis Type MX-10160. Non-gated. I'm guessing ITT made tube from 2005? Performs like an Omni VI non-gated tube. Pretty darn good performance in the dark. Gives my omni vii mx-10130 pinnacle tube a run for its money.

How well do the anvis tubes hold up against recoil on say .223?

OK, let us start with the second tube here which is a ITT F9800RG tube. A simple search will take you to the ITT website which tells us what the tube is. This one is easy. It is a ITT MX-10160 autogated Pinnacle tube. I will add this to our list. The link below shows different models of these tubes with specs.

http://www.nightvision.com/products/files/2005914850170.mx10160_f9800_domestic.pdf

All of these are ITT MX-10160 tubes. ITT F9800K and F9800L are not gated tubes. F9800AG, F9800WG, F-9800RG and F-9800VG are all autogated Pinnacle tubes. The F-9800WG is a weapons grade tube and if you look at the halo spec you will know why.

Tubes are just like ice cream with many flavors and types for different customers. Some tubes have lower specs for export purposes, others may be designed for rifle scopes (weapons grade). ITT and L3 have many different models of the same tube for different applications.
