Hi John:you might want to do a serch on the MQ forum for the SJPC 60... from memory this Special Japanese Plate Choke was designed to produce > 100 henries of L while carrying sixty mils of dc plate current.
it's not in production right now... we build them for an overseas customer... but check it out and see if it might meet your needs.
If your current requirements were 40 mils... then the Dowdy plate choke (125H at 40 madc) might be the ticket.
gotta go,
msl
