Gain in GG depends on plate voltage and drive power.
If we use the example below 8171 can give 15 dB gain.
That is way more then 12% of full output for the tube.
EIMAC states about 16 kW max output in AB1.
Anyway, this is way too much for ham radio use, donĀ“t
even think about using power levels like this!!

A 200w transceiver will drive a 4-1000A in g-g or an 8171 in grid-driven.


It will also drive the 8171 in g-g!

Yes, to roughly 12% of full output.

No a lot more then that!!


An 8171 has about 20db gain in AB1 grid-driven service. How many db gain does it exhibit in g-g service?
