The 3CX10000A7  3CX10,000A7 vacuum tube is a high –mu power triode is intended for use as a zero-bias Class B amplifier in audio or RF amplifier, CW or modulated.

Operation in 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 twenty times can be obtained with the tube.
