CAT3 cooled anode transmitting triode
This is a liquid cooled anode triode with a bright emitter tungsten filament. Water cooling at not less than 2.5 gallons per minute is required. The anode and filament seals require air cooling, and there needs to be air blast cooling of the grid seal as well. See also CAM3
*: At Va=10kV, Vg=0
Markings on the valve indicate 18.4V filament for 5.3A emission at 90% saturation. The serial number is 255.
