There may be lots of NOS or NIB tubes around but try finding a truly NEW late 1950's early 1960s Siemens and Halske Cca 6922 grey plates or a late 1950's pinched waist Valvo Cca 6922. Abot a decade ago a dealer told me NOS was anything that still tested OK, and NIB was anything that tested OK in any box. Just look at the pins... they tell a tale and beware fakes. You can print just about anything on anything.
Are all of these NOS tube inventories real? How have we not consumed them already?
As I've been shopping for new tubes for my preamp, I've really begun to wonder, wouldn't the current and recent population of audiophiles of the last few decades have bought and used up most or all of these vintage NOS goodies from all of the current inventory, secret stashes and newly discovered cases of NOS...?
