Thanks for that, Larry. It gets a bit "Gee whiz aren't tubes wonderful" 
towards the end but the manufacturing sequences are great.

I had this link sent some time ago about the Mullard factory at 
Blackburn. It shows similar manufacturing but of the later style of 
valves with glass bases. The firm
hosting the video have restarted manufacture of the classic audio valves 
- at a price!
