Power Grid Tubes (Triodes & Tetrodes)
 
 
 
Power grid tubes are used in radio communications, transmitters for broadcasting and other applications, and in industrial high-frequency apparatus. Toshiba Electron Tubes & Devices' products service an extremely wide range of frequencies, from direct current to several 100 MHz, and power of up to several 100 kW.
Toshiba Electron Tubes & Devices supplies the market with forced-air-cooled triodes, water-cooled triodes, vapor-cooled triodes, forced-air-cooled tetrodes, vapor-cooled tetrodes and oil-cooled tetrodes.
