Jeff,All,
Is your"custom two part electrical resin " available to normal guys like the
REST of us ?

Plans MAY be in the works(hopefully - depend's on $$)
for a 2500Kva  4160Vac 3 ph  generator powered coil.
I'm cross'n my fingers and if I still have my pant's left on my butt,I'm
gonna need some design help.Are you or anyone else willing ?? V
doubler/tripler,Res. chg. DC.???
