Re: That '22 mH' choke may have an inductance of 22 mH at 10 KHz, but not at 120 Hz.

Correct me if I'm wrong here, but all the references I found state inductance is linearly proportional to permeability and effective complex permeability decreases with increased frequency for a number of reasons. That 22 mH device should have more inductance at lower frequencies, not less. It's interwinding capacitances should be small enough that it remains an inductor well past the operational limit of near any OPT, save maybe a Plitron.
