[Amps] Vacuum

[Will Matney]

Sam,

10 atmospheres is 146.9 PSI. I could actually see this on some large power tubes. Especially tubes with fin cooling as the fins act as stiffners. Since the area that would be under pressure isn't very large, probably as tall as it is wide inside the anode, it would most likely hold it ok. One would be suprised how much pressure things (according to the material) can hold. That's my guess on it, but I will find it and post the results tomorrow.

Best,

Will
