The Vacuum Tubes Last Stand!

Enjoyed reading the texts and watching the videos. Thanks!

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.
