Well I have a K3/10 and KXPA100 with fw vers 5.60 (yeah I need to update).

K3/10 gets 10w on 14-MHz and 8w on 50-MHz.  KXPA gives 100w on 14-MHz 
and 80w on 50-MHz using  a Bird43 meter with a Bird dummy load.
Into an antenna power is dependent on match (as one would 
expect).  The KXPA only needs about 5.6w drive for full output on 
14-MHz but requires full 8w drive on 50-MHz.  Overdriving causes the 
3-dB attenuator to switch on.
