cꢍaRacteRistics
The 3CX10,000A7/8160 is a high-mu power tri-
ode 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 simplic-
ity by eliminating the bias supply, and in addition
grounded-grid operation is attractive since a pow-
er gain as high as twenty times can be obtained
with the tube.
