>The comment about staying in the socket in airborne equipment makes good 
sense. I had always wondered why the 832A/829B/3E29 used such a convoluted 
glass and complicated socket.<
The ability to stay in the socket under vibration conditions is surely more down to the socket design. And retainers weren't unknown in WW2!
807s were used in some British military equipemnt: some were made over here with white ceramic bases, too, but I don't believe the diffrence in RF performance was noticeable.
