[Elecraft] KPA-500 "Output for Input" schedule?

[stan levandowski]

The documentation on the Elecraft site says the KPA-500 requires 40 
watts drive for full output.

Nowhere (at least not that I could find) is the minimum drive 
requirement specified nor is there any schedule of "output for input" 
such as 40 watts = 500 watts; xx watts = 250 watts, etc.

More to the point -- can a K3/10 or a K2/10 be connected to the KPA-500 
and deliver something between 75 and 100 watts output?

??

Thanks,
