Are all of these NOS tube inventories real? How have we not consumed them already?

Note that new tubes, or "currently manufactured tubes" for those who are seemingly confused about what NOS actually means, make up a lot of tube stock (not to be confused with "tube socks"), especially guitar and bass amps (of which I am certain use far more tubage than hifi)...making lots of room for the classic tubes of yesteryear to be used and eventually used up. I use both new (Gold Lion, KT120s, etc.) and NOS tubes because I can...people who don’t own any tube gear should still have a few tubes around simply to look at and because they will make anybody at least "seem" more interesting.

NOS Mullards 12AX7 is an ECC83. Stock piles are though the roof of ECC83. They have a ways to go, to hit Tellies silky smooth old school valve sound, THAT is an ECC83. A 12AX7 that can hold its own and better most is the black plate RCA. yet the grays suck from the same time frame. GE 12AT7 gray plate, will best a lot of the the new stock.. Their problem, LOL they would do the under water deal.. Weird valve.. Good sound weird valve. Easy to figure that one. Tap test the valve at low volume. They will act up..  I'm tinkering with PSVANE too, that valve is really starting to peak my interest.. TAD is different to..close to JJ they have their place..

One of the deals of all time was an organ, left to me with a case of valves.. I had to pick it up in Texas. I long sense gave the organ to an up and coming church... I kept the valves..And put in JJ and EH. Still using it 5 years ago.

The valves are hamon volvo, tellies and baldwin, also where I learned about gray plate RCAs. YUK..

I have about 10,000 New Old Stock tubes in my collection as spares.  No, they are not for sale.  Unfortunately, most are not audio tubes - they are spares for my old communications equipment collection, another one of my hobbies besides audio!

Wow very interesting and thanks everyone!

Sounds like there indeed are that many real examples of NOS tubes out there and some have literally stockpiled enough to take them to the grave. 
@dill if you could take a pic or two and post, it would be wild to see even a fraction of the 30k tubes in that collection. :) 
Continued happy listening! 

Personally I think that there are plenty of NOS tubes.  But it seems the dealers deal them the same as the DeBeers family deals diamonds.

I have had nothing but good experiences purchasing tubes from Upscale Audio.
