Daca functiona pe incinte de 8 ohmi nu se intimpla nimic... curentul la iesirea amplificatorului este dublu in cazul boxelor de 4 ohmi fata de boxele de 8 ohmi. Daca desfaci aparatul poti face niste masuratori sa vezi daca apare Vcc la iesirea amplificatoarelor si sa spui cum sint realizate etajele finale (tranzistori sau IC).

Am rezolvat toate tranzistoarele erau bune dar dupa ce am desfacut placa de baza am observat cablajul inpuscat . Am refacut legatura cu un strap totul merge bine .
