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?

Lost art. That's why. New stuff can be very good, but will always be different. I wish some of these way-to-damn-rich philanthropists would occasionally pick a dying (beautiful) technology to keep alive (like vacuum tubes back in the 60's-70's) -- rather than the trendy shlock they typically flock to -- in order for future generations to rediscover some of the beauty and knowledge that has been created by our predecessors.
