So going through a batch of 60+ tubes or so, a special order for one customer in particular finally arrived as well. The last time I saw specs like this were in a CNVD/LR with one data point higher at 42 S/N. No I cannot show the data sheet so for a "select few" (you know who you are) who won't believe, it's all good. Anyhoot, customer waited 4 months for this tube to go into our TNV-14 build for him. I talked with him on the phone last night and he is a bit happy with the following.
Signal to Noise: 41 Line Pair: 72 EBI 0.7 HALO: 0.74 FiOM: For those with a calculator = 2952. My personal TNV-14 is 39.7 and 72LP was in a "normal batch" a few years ago. I know a few other customers have other 39's, but this tube was special...Oh and for spot size chart... Zone 1: 0 Zone 2: 0 Zone 3: 0 Probably the most perfect tube I've seen and I've seen a few since 1994. |

So would you say about every four months is sorta average of a customer requested this?
|
|
|
Dayum. I'm going to need to figure out how to swing another set from you guys.
|
|
So are all 60+ tubes for that "special order" ?
Trying to tell us now is the time to change our existing filmed orders to filmless ? |

I'd imagine that a CNVD/LR with a S/N of 42 would be positively exquisite. Do want. View Quote View All Quotes View All Quotes Quoted:

That’s crazyness spec wise! I’ve owned tubes up to 72lp/36+ myself. Honestly, I couldn’t see much if any difference compared the 72lp/34 SN tube I owned so ended up keeping the 34SN tube because it was better screen cosmetics sold the 72lp/36SN tube for a premium.
40+ SN is crazy though |

Sounds expensive. Typically, if someone wanted to get on a waiting list, what kind of % should one expect to pay for those types of specs over a typical L3 Chrome tube? Asking for a friend in case he ever wants to save up and shop for some super super tubes. @TNVC |

Those are amazing specs!
Filmless is leading, no doubt, and will probably stay this way for another couple of years at very least. |

Quoted: Every 4 months? You mean every day around here!.... Average spec our Filmless in the 30's. The others we special order are special...If the customer is willing to pay the pricing and wait the wait, we can get some amazing tubes from L3 direct. Edit, I've said it before (and NO Kool-Aide here), L3 is producing the HIGHEST spec tubes I have ever seen in my lifetime period. They beat down all the rest, and just reporting facts from working with night vision and tube manufacturers since the early 90's from my days in LE, Govy, Contractor, to present day operating TNVC since 2005. They have cracked the code on their filmless stuff. It's that good. Every time I think I^2 tech may get aged, I get surprised. I have been told, (NOT seen the data sheets) from some Mil advisors from L3 that 3100+ FOM's are out there. |

something also to be mindful of in these threads with ultra high spec tubes
I would say 90% of the population would have trouble even telling the difference. The folks that use nvg's alot could probably tell you which tube was better but you really have to know what your looking at to notice it. obviously every little bit helps but I personally feel like the price difference between a "good" tube and a "unicorn" tube is quite a bit for that extra sliver of improvement. Then again we all value money differently too, to some its worth it. |

Quoted: In some instances yes, I agree with a few data points...But when it's really dark out there, I surely see the difference with a 39-41 S/N vs. low 30's vs. ANY other tube including Photonis. We are talking just about a FOM 3000 tube. In the CNVD/LR that had the 42 S/N, and 82LP I looked through, it killed it out in the field! There was no comparison. View Quote |

I've had several emails asking us "who builds our PVS-14's"? Here at TNVC we build everything in house, we DON'T rely on another 3rd party who just changes hands and calls it their own. In the VERY unlikely event your TNV-14 unit may need service, we do it in house and also do NOT have to send out to a 3rd party. We control ALL QC and also don't rely on a 3rd party is another reason our PVS-14' have some of the best specs out there.
This is an important question when you spend thousands for a PVS-14 do always ask, it pays huge dividends in the end. |

How does this play in a bino? How close in specs do they need to be before it’s a problem?

Quoted: We usually try to get very close with signal to noise ratios and spot on with line pair rez. View Quote |

About to place an order for a mono mod3 to be upgraded to bino later. I haven't email to ask the price but if I did wait on the higher spec tube how would it effect trying to match that tube later. Would it still be 90-120 or possibly longer? View Quote View All Quotes View All Quotes Quoted:

Quoted: Sorry just saw this...These special tubes we order are guaranteed at 40 Signal to noise or better and 120 days + out, along with a high price. Waiting for the luck of the draw at a 39 Signal to noise normal delivery could be a looong wait and no guarantee. View Quote |

I can't imagine 40+ SNR, my 36 WP filmless is basically cheating. The last few nights here have been clear, plenty of moonlight, and windless. My 14 and KN203 are getting a workout. Tonight is mostly clear with a 100% chance of suppressed subsonic 22 LR @ 200-250 yards

Quoted: Yeah that is pretty cool. View Quote To those looking to dump your current NV for WP; if you have a nice green gen 3 unit w/ good specs, I wouldn't necessarily kick it to the curb and spend a bunch of money to "upgrade" to WP unless you just have to have the latest thing. The law of diminishing returns definitely applies here. I don't regret my purchase at all, but I have yet to encounter a situation that my supertube can handle that any of my 50+ prior green tubes couldn't. |

I have an example, reading vehicle license plates at a distance. An old PVS14 thick film cant do it well. Too low of resolution, too dim, if you add light, too much bloom.

I have very little understanding about all the specs posted but it’s very interesting. Any chance you plan on doing factory tour or assembly videos that explain how you make these and what is done to go from a regular to a super tube?

i would hope these are also assembled in a filtered, clean room, environment, which also does not lend itself well for guided tours. i know when i assemble any of my stuff, i take the same precautions as when i am working on exposed hard drives for data recovery, which is probably overkill, but i already have a space set up for it. nobody likes dust bunnies behind the optics. :-)

@TNVC
I'm working with Kirsten on a quote for super tube RNVGs. She's super helpful and great to deal with. Is she the right person to discuss the technical details of the tube with? I have a few questions about how the tubes are selected and what is received after placing an order |
|
I really want to jump on the L3 wagon but I'd need to use them out in the boonies for myself. Matching them up against my hand selected Harris HP+'s over a few moonless nights I would know for sure. It's a dark sky location with no city glow. I'd absolutely be pissed at myself to spend the money only to find the difference minimal because I need to sell stuff off to keep wifey happy and I like all my tubes. I keep listing shit but nobody wants green and I ain't giving it away. 1st World problems, eh?
