Single shot tube tester ?

[saturated]

Seems like a person could take one of these

You cannot view this attachment.

And build the appropriate circuit needed to test

I reckon simplest example would be a diode rectifier tube.

Just add one of these old power supplies that has the 400 (?) V DC and  6.3 for the heater

Downside would be extremely limited application per configuration

Upside would be the lack of a million knobs and switches and stuff some of these testers look like an enigma machine from Blechley Park

Another downside would be getting killed by 400 V DC

It would be cool though seems one could learn quite a bit from it if he/she survived 

But then me thinks that someone could spend time and money doing it then one of you guys could tell more in 60 seconds with a multimeter
