The CV372 is a (triode) hydrogen thyratron for pulse modulator duty. The prototype was the VX4027. It would work with a peak anode voltage of 3 kV and a pulse power of 60 kW.It was originally used in some WWII small airborne radars but remained in the lists until the late 1970s.The commercial equivalent type is FX227.In-service life was rather short so the valves had to be replaced quite frequently. There are plenty of relatively modern specimens around, mostly in unused condition, but WWII originals are now rare. Modern specimens include a small hydrogen reservoir cylinder absent in the originals.The electrodes are firmly held, and the stout wire to the top cap is insulated by glass. The filament is vertical within the anode. The construction has a pressed glass base.The wide glass tube envelope is 36 mm in diameter and, excluding the UX4 base pins, is 106 mm tall.References: Data-sheet & Private communication. |
