Product Description

Vt4cx150f electronic tube is a side heated oxide cathode and a forced air-cooled cermet quadrupole. The tube plate has a power consumption of 250W. It can be used as power amplifier, voltage amplifier, frequency modulation, frequency doubling and oscillation tubes in radio equipment such as high-frequency equipment, FM broadcasting and single sideband communicators. It can be interchanged with 4cx150a electronic tube produced by eimac company of the United States.
