The 3CX10,000A7/8160 is a high-mu power triode and is intended for use as a zero bias Class B amplifier an audio or RF applications, or as a Class C amplifier, CW or modulated. Operation in a Class B with zero grid bias offers circuit simplicity by eliminating the bias supply, and in addition grounded-grid operation is attractive since a power gain as high as twenty times can be obtained with the tube.
