    …incercati si voi si spuneti-mi parerile voastre..
    cateva rectificari: sarma poate fi de : 0,10 – 0,20 mm,la primar,si se bobineaza prima pe tot inelul de
    de ferita,si de el se fac legaturile la bec, (eu am bobinat 400 spire bifilare)…
    …. 0,50 – 0,70 mm, la secundar,( eu am bobinat 25 spire bifilare),si se bobineaza peste primar,si se fac legaturile la circuit.Bobinajul,atat la primar cat si la secundar,eu l-am facut bifilar,am mers cu 2 sarme deodata,iar legaturile,atat la primar cat si la secundar , le-am facut ca la o bobina tesla,adica capatul primului fir se leaga impreuna cu sfarsitul de la al 2-lea fir,si se folosesc pentru legaturi celelalte 2 capete care raman…..
