[Elecraft] K3 Power puzzlement

[Ralph Parker]

>I get about 4.5mA with my K3/100 powered off...
I would have expected something similar, if not zero.
I always wondered why I heard a 'pop' from the speaker (audio amp?) when I
plugged the K3 in with the power off.
Could be related - a leaky cap charging?

>Assuming you've checked the obvious (...nothing else connected to the p/s)
Yep. The meter (Watt's Up) is in the 13.8v line in series with the K3.
