What the title says. Not directed at any particular listing, but I've seen this a few times recently. Doesn't the "N" in "NOS" mean "New"? As in, unplayed? As opposed to used?
Personally, I find it hard to believe that this is even a question. NOS = New Old Stock. New + Never used. If it has a "few hours" on it it has been used. therefore it is no longer NEW and it can't be NOS. ANOS?!? What is that? Actually Not Old Stock? What a load! If it's an old tube and has been burned in to test against "infant mortality" then the seller should say such and price it accordingly against genuine NOS tubes. Maybe the guarantee of no "infant mortality" has some value in the marketplace. Maybe it doesn't. Whatever the case, if it's burned in already it is NOT NOS and should be sold as such.
