EIMAC 3CPX1500A7/ PULSE RATED 8877 TUBE

Description

Up for sale used Eimac 3CPX1500A7 -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 high peak power is required.
Tested on my 2m Amplifier
(W6PO design) (my callsign YT1AR).
It delivered about 1390W RF OUT(Bird 4314-2.5kw slug) (3200VDC on anode-abt 70w rf drive) ) on WSJT with a low tube temperature
after 50 seconds continuously transmitting.
