Lynn,
The K3 or KX3 measures the total current draw with quite reasonable
accuracy.

I'd expect the internal meter to read current into the finals, which
probably dates me pretty thoroughly to a time when "finals" was nearly
always preceded by the word "tube."
I can't check the K3 manual to see what it actually measures because I
don't have one. I have a KX3, and a huge 7a power supply to run it.

Gosh Engineers...why not just suggest to Paul that he use the most

method of finding out the voltage and current the K3 draws by
pressing the
K3's METER button????

Here is how I'd do it, your mileage may vary.
I'd measure the power draw at 100 watts key-down, and the power draw for
receive.
