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?

The tube manufacturers of today have lost the "old formulas" for making quality tubes. The Russian tubes of today were formulated on "Military" tubes designed to keep Migs flying through "atomic clouds"!
