Vt4cx1000a electronic tube is an oxide cathode, forced air cooling, cermet structure and beam power quadrupole. The maximum plate consumption is 1000W. Because of its high gain, it can be used as a class Ab1 RF linear amplifier or audio amplifier. When the rated maximum anode voltage is 3KV, it can generate 1630w peak pack output power. Two vt4cx1000a tubes work in class Ab1 and can produce 3260w audio power output. It can be interchanged with 4cx1000a electronic tube produced by eimac company of the United States.
