Electron tube   3CW20,000H7
The 3CW20,000H7 is a high-performance ceramic/metal, water cooled power triode designed for use in zero-bias class B RF, audio amplifier,DC voltage or current regulator, or high voltage pulsed or switch tube service.A modern mesh filament is used, replacing the old-fashioned hairpin construction.The improved mesh filament design ensures better mechanical rigidity and long lasting concentricity of the filament, providing enhanced linearity, less noise,reduced warm-up variation and longer life. The low-inductance, mesh-filament basket also forms a natural extension of the cylindrical stem geometry into the active area, giving superior VHF performance to 200MHz. The anode and grid flanges provide ease of mounting regardless of application.
