I just looked at the current values of my K3s using the internal DISP
current and voltage values.
This is how it came from the factory after replacement of the KPA3A
rev E amp on 5/30/2018.
In RX USB mode = 1.6A Vcc = 13.8V Audio volume at minimum.
<<note correction above>>
In TX USB mode no audio, 10 watt PWR setting = 1.60A Vcc = 13.7 V
In TX USB mode no audio, 100 watt PWR setting = 2.91A Vcc = 13.6 V
The PWR delta is 1.31 amps
In RX CW mode, = 1.03A Vcc 13.8V Audio volume at minimum.
In TX CW mode PTT closed, key open, 10 watt PWR setting 1.54A Vcc 13.7V
In TX XW mode, PTT closed, key open, 100 watt PWR setting 2.85A Vcc 13.6V
The PWR delta is 1.31 amps
Your values may be different if you have the 2nd receiver and may
slightly vary depending on your Vcc.
