[Elecraft] D 104

[Grant Youngman]

That would be a COMPLETE AND TOTAL waste of time. The K3 mic input Z is 600 ohms nominal per spec. 

The D-104 element needs 500k minimum and better no less than 5M. Last I heard the input stage of a K3 was not a 12AU7/12AX7. 

That's why Z transformation (preamp, xformer) IS required for this element
