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?

Simple and short answer...The demand for vacuum tubes is not great enough for a manufacturer to lay out big bucks for production.Just my opinion,others will disagree and that's fine.
