I don't know what the problem with NOS / good used is besides that some of you are buyin' em from dirtbags.
Here's what happens: Some Golden Ears hi-fi pervert spends $300 for a pair of Mullard, Telefunken or Amperex 12AX7s. Seems to me the Telefunkens are the flavor of the week mainly 'cuz that what's hot in Hong Kong, if it has that little diamond on the side it's worth the big bucks, right?!
So ol' Golden Ears has this big ol' cigar box full of 12AX7s. He digs through 'em, sticks 'em in 'is $70,000 super gold plated spent oh so much more than you can imagine to get that one percent extra hi-fi rig and sorts 'em into great, good enough and Hoover style suck categories. Obviously he's gonna hang on to the "great" ones but the ol' Hoover styles go right back on FleaBay, heck, with those gold pins and the original boxes they must be worth it, right?!
O.k., so you just spent Golden Ears hi-fi pervert money for tubes that sound like Hoover style suck. NOS sucks, right?
Well, I go out and beat the bushes for old caddies full of tubes, I buy a zillion old tape decks, I crack open all sorts or surplus crap and once the light scares the roaches away I see Mullards... and Telefunkens... and Bugle Boys... and RCA black plates... and more pedestrian stuff like '60s GE, Sylvania and Tung-Sol. Some is NOS, some is good used. It don't matter to me, by the time I sell off the extras 'cuz I got WAY more than I'll ever use it's all damn near FREE!
There are only a few types that I'm hoarding and here they are: I hang on to 5751s because they're not an everyday find in the gear I'm crackin' open. I hang on to Mullard EL34s 'cuz they kick ass and again, they're a rare find among my various sources, pretty much I have to buy a caddy and hope that pair in there actually matches! I'd like to get a good pair of Telefunken EL34s "just because". I hang on to Mullard 5AR4s 'cuz I dig 'em.
I actually paid money for 6CA4s the other day. I paid $3.00 each and they are NOS.
EL84s and 12AX7s? Heck, I get a ton of 'em an I got a ton of 'em! I'd just about give 'em away except once word got out I'd have a damn rut beat to my door that looks like the Grand Canyon!
