While I was doing some research I found a couple of pages of pictures showing how a couple of tube are made. Its two pages showing a couple of tubes including a 300b. It was kinda interesting so I thought I would post it.

Pretty amazing and considering most tubes are rather inexpensive yet all hand made. Hopefully they never go away. Great stuff.

A prior How Vacuum Tubes Are Made thread here.

Way back when starting to think about what was to become the CTH, we'd considering limiting the design to subminiature tubes & I stumbled across this neat video about them.
Thought it was strange Raytheon was making them into the 1980s but old designs die hard in military applications.
