[Amps] Gassy Tubes/Technology Museum looking for artifacts

[Pat Barthelow]

Folks:

I grew up in the early era of Mr. Wizard, Renwal Electrostatic Generators, 
crystal Radios, and Heathkits.   I  know the TWO distinct differences 
between an 807 and a 1625 tube.   I also know an ARC- 5  when I see one.    
I suspect many here know these artifacts of Technology history, too.

While looking for information about residual gas in transmitting tubes, I 
found this article, a very good read:

After reading this, I looked to the root source of the article and found 
SMECC ,

look through your junk boxes to see what yoiu can cotribute to their 
Mission:
