This valve measures 355x210
overall and weighs 4.8kg. |
This valve has thoriated tungsten
filament. It is a modified version of the CV1583, which itself was based
on the E1024/CV1114 or VT114 valve which replaced the silica NT77 in the
MB2 mobile ground radar system.

The filament leads required
cooling with at least 10 cubic feet of air/minute, and the anode required
forced air cooling of at least 85 cubic feet/minute.
The valve was intended to be
operated at a constant 70A filament current, with the filament voltage
being adjusted between 9.3 and 10.7V.
