The Vacuum Tubes Last Stand!

Thanks for sharing!

The problem with this article is that it implies that the vacuum tube is dead.  How so in light of the number of new devices that rely on vacuum tubes are introduced even now?  They still have application in aerospace not just audio.  

I think the better title would be "Arrested Development."  There has not been much in the way of developing new tubes, much less tube types, in recent times.  

Vacuum tubes still used in aerospace ? I didn't know that.

I think, tubes will continue to be present for the foreseeable future, and overall more people are getting interested in vintage technologies - vacuum tubes, tape decks, turntables, books, handmade things.
