The 3CX10000A7 is a forced air cooled in anode, ceramic-metal power triode containing a thoriated tungsten cathode which is designed for mainly used in AF or RF applications as a zero grid bias amplifier in class B.The tube get a simply circuit as operation with zero gird bias since eliminating the bias supply. In addition, grouded-gird operation is attractive since a power gain as high as twenty times can be obtained.
