Why aren't new vacuum tubes as good as old ones?


Why aren't new vacuum tubes as good as or better than old ones? Don't we have purer metals? Precision equipment? Why isn't anyone making the highly regarded 7316s?

jyprez,

You don't need the data, all you have to do is listen to NOS vs. New.
I have Mullard NOS tubes from England. These are FAR better than the newer tubes that came with my amp. Not even close....
