Using IV-22's

[Jonathan Peakall]

Hi All,

Just picked up some IV-22 and want to play with them without destroying
them. I have Dieter's translated data sheet but I still have questions:

Filament voltage says: 1...1, 32V. Huh? I seem to remember that you can
use a D battery for the filament and the filament is pins 5&12.

DC grid, is that pin 6 with 22-30V on it, limited to 6-10mA?

Segments, also 22 to 30V, limited to 4mA?

Thanks!

Jonathan
