Thanks so much for the Dissection! I wonder if one can wind the coils with the same wire gauge and turns but using a nowadays commercial lam and still keep more or less the same transformer behaviour.
I want to build a copy of an Altec 436, or better, EMI RS124, but where I live, to pay for a Lundahl or Sowter Trasformer is nearly impossible.
Do you guys know some simmilar L lam?
