Default bias circuit for mosfet help

I am using a 1:1 input transformer to a mosfet source follower. The 1:1 will not have any secondary resistor.... just connected direct to gate of mosfet.

so one end of 1:1 is connected to gate... the other end of secondary to bias.

I need to design a simple bias supply using a 6vdc or 12vdc battery that will not load the 1:1 transformer in any way.

Any help?

looking for simplicity... i.e a couple of resistors and a potentiometer...

remmeber this is just for testing.
It is not you... you are it.
