So what is the opinon here of NOS tubes? It seems that a lot of people won't even use new tubes being made (which makes you wonder what's going to happen in 30 years when all the NOS tubes dry up). It sounds like a typical thing to create hype over, that old "they made things better back then" thing, but is it true? I currently don't have a tube amp, so any tubes are still a step up from the oversized POS I currently own. It probably is irrelevant to me anyway, I'm not sure how many dealers in Aus stock old tubes.
