They exist in those sizes, there is a Solen 3.7 mH perfect lay and a Solen 3.6 mH hepta-litz, for example. Erse has a 3.6 mH perfect lay.

Everyone is just out of stock. Madisound said there has been a run on those values lately.

So what do you do, measure your final induction value with an LCR meter? I could do what you do, get a larger size, it seems like a good idea, but I don't have any way of measuring the inductance that I know of, without buying a meter or signal generator.

Actually, I just checked, and there is this technique which measures the voltage drop across a resistor:

I'll think about it. :cool:
