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.
