Is this a pinnacle tube?

What does the actual tube say? The NSN is for a PVS-14 and the tube spec is for a MX-11769/UV

It's contract date was around 2001/2002 so it's more likely to be Omni V than IV.

If that's the case, then it's not a Pinnacle as far as I am aware.

But it's close enough to introduce some doubt. I'd say check for autogating. If it's autogated, then it's probably a Pinnacle.

This PVS-14 uses a standard film non-autogated tube. That means not a Pinnacle, although late production.
These tubes are very good, though...If with low EBI, I like them more than Pinnacles...

Where do you see a contract no, David?
I have seen few of those, they were all without Contr.No., most likely some cancelled order. Or FOM limited tubes for export.
Link Posted: 1/22/2011 8:24:25 PM EDT
how do you determine the born on date?


and what numbers indicate non autogated?



can you see a difference looking throught an auto gated and non autogated?

Part A3256350 was manufactured under contract DAAB0701DN413 (L3) or DAAB0701DN414 (ITT) - Both are Omni V.

Your CAD can be considered your born on date, well at least when your birth certificate was issued. So your tube was accepted the 43 week of 2007

The part number indicates whether it is gated or not. If you are in anyway doubtful, you can do as David said and listen for a whine or perform a simple test as demonstrated by this video; http://www.youtube.com/watch?v=2ike1VsbI7o

David,

Where did you look that info up at?



I have 2 more tubes I was wondering about? Are these pinnacle?

first:

ITT 272876-9
DC 0817
SN 451756

Second:

ITT 272867-9-046
DC 0629
SN 029890

that is the only info on these 2 tubes I can see without taking the tube out of the body.

OK guys, pens handy... I'm about to reveal a secret source...

Drum roll please...


Tada!

OK, well maybe it's not that impressive but it's a damn good place for information on military tubes. Just get an account and start browsing.

As for the others? Either insufficient information or they are not military tubes.

David

If it's a night enforcer, then try asking the reseller - They should have datasheets now -

both of these have a high pitch ringing sound when you put them up to your ear. Best way to describe it is it sounds like when you have been at the range all day shooting and you leave and have a slight ringing in your ears, That was the closest thing I could think of that it sounds like.

I do not understand the you tube test???

By starving the Autogated tube of voltage it causes the image to strobe. It is a simple test CompassCall came up with to help tell if a tube is AG. Most AG tubes produce a faint whine. This is the easiest way to tell. Some AG tubes are almost dead silent and other testing may be needed. Litton tubes in particular can be very quiet and are sometimes difficult to tell if they are AG or not. I have a Litton AG AEO tube that is dead silent but is a AG tube. My ITT tube is very quiet and my ear has to be up against the scope to hear it whine. Some are louder then others and is just the nature of the beast.

how do you starve it of voltage to test it? Both these two, you have to put to your ear to hear the ring I am hearing from them

Being that it is CompassCall's invention I will let him explain. He will see this and explain it to you. There are exceptions, scopes with a voltage multiplier can cause issues and some other tube safety measures need to be followed. It is better he explain this as I don't want anyone to damage their tube by giving bad information.

I have a basic understanding of the process but better to get it from the source.
Link Posted: 1/24/2011 12:44:39 PM EDT
is the ringing sound i hear, what you are referring too, to verify they are AG?
Link Posted: 1/24/2011 1:19:14 PM EDT
Yes, the whining you hear is a AG power supply. Non AG tubes are silent. That said some AG tubes are pretty silent also which is why further investigation is needed for some tubes. I would of bet money the AEO tube I have was not autogated. Turns out I was wrong and it is. The tube is dead silent. Milspec tubes are very easy because the contracts can be tracked. Commercial grade tubes sometimes have tell tale numbers on the casing or power supply but sometimes you will find no markings. This is where CompassCall's test can be very useful.

Only partially correct. A3256350 were delivered under DAAB07-96-C-J209 OMNI IV contract, as well.
Plus count in DAAB07-98-C-J418, DAAB07-98-C-J419, F19628-03-0-0021 plus other countless deliveries not assigned under any specific contract just like this one.
Generally we can say that A3256350 is a standard-film non-autogated MX-11769 no matter what production date..

Both are autogated Pinnacles...

Last Lancer is a walking encyclopedia of night vision tube contracts. He has collected the information for many years, I am sure it is what he told you. Contracts can be looked up online. It takes a while but all those numbers on a tube mean something. He has lots of years under his belt researching it.

I have not found it in the sense of word you might expect. There is no source that would help you reveal this, I am afraid.
Dino is right, I have spent years collecting all available info. That included saving all pictures, writing down all found records, comparing serial numbers with power supply types etc. No one has "taught" me this but many fine guys on various NV forums have helped a lot by providing info about their tubes.

After a while the whole system starts to make some sense. Most tubes are easy to comprehend now but I dare to say that there are 5-10% tubes which still give me headache. ;)
Yours are the easy ones :)

Care to check the numbers scratched on the sides of your tubes, in return, and provide me with info for my database?

Link Posted: 2/1/2011 7:16:46 AM EDT
sure, when i get alittle free time ill open them back up and check for ya.

I am not doing the nitrogen purge, will I be ok without it?
