The electron tube 3CPX1500A7 is a rugged high-mu power triode, designed with beam-forming cathode for pulse modulator and so on.

Electron tube 3CPX1500A7 is a rugged high-mu power triode, designed with beam-forming cathode and control grid geometry to allow the simplicity of design and circuit advantages of a triode with the gain of a tetrode. The tube is intended for pulse modulator or pulse regulator service. The external anode may be forced-air cooled. Or, for increased high voltage holdoff, the tube may be immersed in an insulating liquid, which is also used to cool the tube. This tube may be used in a grid or plate pulsed RF application where the high peak power is required.
