I'm sure that's a good one. I have close to 100 12AX7s as a result of buying out stores and companies around New England in the early '90s. My best haul was 55 Telefunken 12AX7s from the Grass Instrument Company in Quincy/Braintree, MA. They are especially good because Grass manufactured galvo based EEG systems and polygraphs and had to cull the noisy tubes. The ones that made it to stock were selected for ultra low noise and had red nipples. I paid $7 each for them which seemed like a lot to me back in '92.
Despite their appeal they are not my favorites. To me they sound a little dry and a little lacking in dynamics. I actually prefer some of the newer versions. Groove tubes does know what sounds good. I have a few of their tubes. The 12AX7s I have from them are the "R" version. I used them in my ASL headphone amp for awhile.
The NOS thing is way overblown imo. Many of the NOS tubes selling for big dollars were end of the road ones from when the companies were closing down and quality slipped. Many of the NOS tubes I bought in the early '90s had major defects. I'm still sorting through what I have. It takes a long time and especially so since I go back and forth between tube and ss.
