[Elecraft] KXPA100 power consumption questions

[Gary - NC3Z]

Hello group,

I am very close to pulling the trigger on a KX3 and possibly the 
KXPA100/KXAT100 combo. If I can swing the KXPA100/KXAT100 I think I 
would not option the KX3 with the KXAT3 at this time. But I have some 
questions.

The manual mentions that with the amp enabled but the power set to below 
10W that the amplifier passes the RF through without amplification. If 
this is the case has anyone measured the current draw of the KXPA100 in 
this mode with just the tuner working?

Also, has anyone measured power consumption at less than full power, say 
25W, 50W? Not sure how bad the efficiency gets as the power out goes down.
