During this period, the development of electron tubes created the so called Electroni Age. Electron tubes played the leading role in the electronic equipments until the middle of the 1950s when solid state devices such as transistors and integrated circuits replaced electron tubes in various applications and accelerated the electronic age.Actually, this system required a tube for high-power modulation, but since the frequency was low, there were no difficulties, and the ... In the former case manufactured by Tokyo Shibaura two WT375 (anode dissipation 40 kW) water- cooled triodes of Tokyo Shibaura were ...
