Grant, Then why not just put a 1 megohm or so resistor in series with the mic element. I believe the K3 mic input has adequate gain to compensate for it, and it will keep the crystal (or ceramic) mic element happy. The KISS principle applies - a resistor is much more simple than an FET or a transformer.
