It is fine to love NOS tubes, but don't have a disrespectful and condescending attitude towards those of us who simply aren't interested in spending gobs of money on supposed NOS tubes. I've been there, done that, know people who have, and there are plenty of tubes supposedly NOS and highly tested that are not what they are being represented as. Speak to Bob at Eurotubes (US distributor for JJ tubes) and he'll tell you this: Tubes can measure as new and be highly used. He has measured highly used old stock tubes and they will have strong, as new, measurements for thousands of hours. Then, they will suddenly show a rapid decline in performance and readings as they approach the end of their useful life.
Ken Stevens of CAT has some pretty harsh comments to make on supposed NOS tubes and their suppliers. Go to the following link: http://www.soundstagelive.com/factorytours/cat/
