WL-530

The WL-530 is a water cooled, 8000 watt, triode with a mu of 21 to 26 that was made by Westinghouse for pulse service up to 120 MHz. The tube could produce a 75 kW pulse. Also known as a VT-122 and 2 of them were used in the BC-400B transmitter that was part of the SCR-270 RADAR system. This was the first large tube to use a Thorated Tungsten filament. One of the SCR-270s was the RADAR that was used to spot the Japanese planes that were to bomb Pearl Harbor on December 7, 1941.
