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?

Hi all ! A tube guy once told me the reason the older tubes sound better than the new tubes is back in the day they could use " nasty chemicals " . Apparently those chemicals make a better tube . Dont really know if this is true or not .
