Ed,

Being the original questioner I'd like to point out, that I've asked for 
the YU 204 which is different from the a.m. 204 tube. The YU 204 
was used by Siemens for a part of a computer tomograph. They 
placed it on a PCB with relatively modern components.Furthermore 
it's definitely not a triode like the historical type but a tetrode.

Unfortunately I've checked a lot of URLs for technical data without 
any success. I'm still wondering if this YU 204 manufactured by 
Triton Electron Technology (yes, I've checked their power grid 
database as well) could be used for a VTTC.
