So, if one needed to build or buy a dozen charging inductors for a resonant charged spark gap coil, where would one look..
It's for an application where there's multiple coils being charged from a common HV DC bus.
Probably need 5-10 H, and it needs to handle a few hundred mA to amp (e.g. 10kW @ 10kV is an amp), and, of course, have a 10-20kV voltage rating.
I'm looking for ideas that are either off-the-shelf or made from off the shelf things (e.g. no scrounging a half dozen MOTs and then sawing an air gap and rewinding it)
(or, some other clever scheme to charge the primary tanks of multiple coils)
