[Elecraft] Electret microphone for K3

Sometime back I bought a W2ENY electret conversion kit for my Astatic mic but I seem to have lost the bias resistor/jumper that came with it and there’s no value specified in the instructions.

I see that the bias resistor used with the Elecraft MH2 microphone is specified as 5K6. As I want to use the (converted) Astatic with my K3, I wonder if this value seems sensible to maintain the correct bias and prevent max bias current going over 10mA?
