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

Funny you should mention this. Next week I am going to look at a collection of  approx. 30,000 tubes (supposedly NOS) from an estate of an avid McIntosh collector. All the gear has been sold, however the tubes remain.

Also from upscale, I recommend the Matsushita 7DJ8

I am picking them up tomorrow. Will keep you all posted on what we find.

Well, I filled up the Tahoe with almost half of the collection. I thought this was a collection that was purchased from an avid McIntosh collector and where mostly NOS. I was wrong. True he was a McIntosh collector, however the tubes are not mostly NOS, but have all been tested with the bad ones decarded. There are quite a few ham tubes but thankfully no TV tubes, plus some really bazaar ones. This is just half the batch so far but I did get a look at his secret stash, now we are talking. Several bins of Genalex, Western Electric, RCA, Telefunken, Mullard, Valvo, etc. all tested on his Amplitrex tester complete with printout. I will be selling those after all the others are gone. Not sure yet if there are 30,000 tubes, however there are certainly 5 figures total. This project will take quite awhile.
