Electron tube_1336_RS3021CJ_DB938 TRIODE

Description

Electron tube DB**8 is a ceramic/metal power triode designed and wildly used in industrial which can be replaced for RS***1CJ. ***6_RS***1CJ_DB**8 TRIODE DB**8 is metal-ceramic triode, of which the cathode is framed by thorium-tungsten, the caged grid is welded by molybdenum filament and the anode is cooled by hypervapotron. Of this tube, the maximum output power is *2KW, and the highest operating frequency is **0MHz; and it imitates coaxial electrodes structure and could service in RF oscillation and amplification can be used in replace of the tube RS***1CJ that is manufactured by Siemens in Germany. 1.
