Today are arrived the firsts FINEMET C nucleus from Hitachi distributor.
Three types for different use, one p-p, one SE and one fro MC step up.
Soon I will have the protos to check and the intention, if they seems fine, is to produce a line of trafos.

ps: it is funny that I am a Hitachi employee ( on computer company inside the Hitachi galaxy)

We are preparing a test set up to check them in deep, the way is the one I described time ago, the "reverse way" that is, in my opinion, the best and efficent way to check the OT trafo
Would that be the 'reverse way' using the wrong impedance on the primary, as pointed out by timpert in that thread and demonstrated by him using both simulation and measurements?
