this is just a DIY print of a L-12 lam as used in the Pultec OPT,
got a request in a PM but you can not attach images in a PM ,
alloy type unknown, maybe 50% Ni, maybe 80% Ni, need a sample to measure inductance, or maybe somebody with a real EQP-1A could measure pri inductance @ 20Hz, wishful thinkin me thinks,
this lam can be approximated with a Mag Met lam from the 12-L family but a min order might be required (big $$)
