The 4CX10000J is a cermet sealed, shock-resistant coaxial-structured tetrode with a mesh thoriated tungsten cathode. Its anode dissipation is 12kw. The tube is specially designed with extremely low intermodulation distortion for use as the RF linear amplifier, which can directly replace the foreign product of the same model.
