Since the United States made breakthroughs in the technology of electron tube tungsten wire laying in the 1930s, high-power direct-heating launch tubes have been launched. At the time, these high-power tubes were mainly used in military communication equipment, but as high-power high-frequency amplifiers. The design of the tube is very rare, and audiophiles have to make high-power audio amplifiers only from high-power launch tubes. Solar Energy System Nut Ground Screw
