I'm so sorry, but we're cousins and should not get married.
You don't want "mH" (millihenries); you want Henries of value. Between 5H and 10H should be fine. I actually have some small-size 7H inductors with a DCR of several hundred ohms. Those would work. You need to know approximately how much current you are drawing. The inductor must be rated so as to tolerate the current across it. Here is where I am leary of asking you to do something potentially dangerous, but if you can safely measure the voltage across the 1K resistor, the calculation is done using Ohm's Law, V = current X resistance. In this case, R is known to be 1K and V is equal to the V on one lead of the resistor minus V on the other lead. Having said all that, based on my own familiarity with the circuit, probably a 100mA rated inductor is fine, overkill in fact. Check the Hammond catalog.
