Depinde cît de mare e trafo, a?a din ochi, raportat la cei 300W de pe etichet?, ar fi 2x60W sinus, cam 2x80-90W la muzical, pe 8 Ohmi.Deci po?i s? cau?i un amplif de maxim 100W/8 Ohmi, alimentat la maxim +/-50V, sînt scheme mai sus.

asa din ochi e cam micut, revin cu o poza mai tarziu si de aia am intrebat ce amplif sa fac ca nu as vrea sa investesc banii in el si dupa aia sa fiu nevoit sa cumpar si traf ca nu e tocmai ieftin
