Would this work with a grace design Felix as well? It can output 12 volts on the tip or the ring. Is the bias resistor still necessary then? (Assuming it works in the same manner as the sunnaudio preamp?)

Felix already supports bias power for a mic, just like the sunnaudio does. So you don't need any special box, or even a resistor. Just make sure Felix is configured to supply the voltage on whatever input you are connecting the electret mic. rschultz is doing this because he's using a preamp that doesn't provide power for the mic.
