[Elecraft] D-104 preamp ...

Does anyone have a design for a FET preamplifier for a
D-104 that will work off the K3 mic bias (rather than the
separate +8V line) and the typical 3.3V mic bias in the
current crop of laptops?

I'd like to avoid providing  separate preamp power when
the mic is connected to a computer soundcard ...
