There are fake or rebranded NOS tubes out there!
I recently came across a "NOS Mullard 6SN7" in Mullard boxes with white printing of Mullard on the glass. "Made in USA"! Mullards are made in the UK, not USA!
These are actually Russian 6SN7s. If you want them, you may pay pesos 500/pair.
Yep! Because Mullard never made a 6SN7, ever!
actually mullard did and it is referred to as the cv1988 and they did made a very limited supply of 6sn7 and theses are rare, however if one is looking for mullard's 6sn7 types best to go for the cv1988 or if one has the dosh, the ECC33 and ECC32 which mullard did make, consequently cv1988 is also made by STC and Brimar. the later brown base ones from the 70's in military boxes are from Brimar. they also come in two designations GT (black base) and GTY most of the cv1988 i have seen are smoked glass for military applications. these are very nice quality if not one of the best 6sn7 type valves available and still plenty of them are around.
i have a few of these in my collection including some very old ones and even a clear bottle one from the 50's in fact i got a pair on my LEAK TL10.1 playing at this very moment
