Nu cred sa iti poata da cineva o asa formula. Cel mai bine ia si masoara sarma originala si cauta pt bobinat sarma de acelasi diametru. Daca ai cum masoara cate spire (sau ce lungime a sarmei) are bobina originala . Daca poti afla nr de spire original f bine , pui exact acelasi nr de spire. Daca nu mai poti afla nr de spire original te uiti sa vezi ce impedanta avea diful (2 , 4 , 6 , 8 etc ohmi). Rezistenta sarmei (bobinei) unui difuzor este in general cam 0.9 x impedanta - deci impedanta 4 ohmi~3.6ohmi rezistenta sarmei . Pt un dif de impedanta 4 ohmi tai o bucata de sarma de 3,6 ohmi si aia ar fi sarma cu care vei rebobina difuzorul . Pt impedanta de 8 ohmi tai 7,2 ohmi etc. Daca mai ai un difuzor exact la fel ia si masoara ce rezistenta are sarma bobinei (adica ce rezistenta are la borne ) si tai o sarma de aceeasi rezistenta. Metoda aia cu taiatul unei sarme de rezistenta 0.9x impedanta originala , sarma fiind de aceeasi grosime ca originalul am aplicat-o si eu si dif-ul a iesit f bine. Sper sa-ti fie de folos sfaturile mele :yawinkle: .
