Hi folks - I'm interested in this discussion as I am in the process of
building a pair of mics with EM-172 capsules for my LS-10.

The data sheet on the EM-172 is implies they should run at five volts
with 3k9 load resistor. And the frogloggers site where I got the
capsules includes this statement

    /The EM172 ECM must be operated at or near its nominal operating
    voltage. Operation at too low a /
    /voltage will produce excessive self-noise. /

I am building a battery box with a modestly regulated supply to meet
that spec.

It sounds like you are running these with PIP and if so, have you
measured the current flow through the capsule? I'd be curious to what
you found.
