[Amps] Question: looking for a design for a simple test fixture for 4-125A

[Robert Groh]

Good evening all. Yeah, I know a 4-125A is too small but I've got three of them 
and a hankering to see them glow.  And to make things worse (?), I found a (NOS) 
socket for them. So what's a ham to do?  I want to see about building a simple 
'test fixture' for the tubes so I can check them out. I'm going to have to 
scrounge like h*** to find what I need (since I sold all the HP pieces I had) 
but, at a minimum, I just would love to find out if these tubes will work and 
pull current and handle some voltage.  


So all ideas would be most gratefully received.
