To be honest I don't know! I'm still working on The drive circuit for
my solid state coil driver. I should have it ready for a test run in
about a week or so. The main output transformer is a push-pull wound on
a large diameter iron powder core. How in the devil would you be able to
test their inductance while in operation anyway? The only way I have of
testing the inductance is with a LCR meter. If you know of another
method please let me know.
