Acum cateva minute am terminat de construit un amplificator cu tda1562. Prima data l-am conectat la o sursa de 200w, de la un pentium 2, si spre suprinderea mea, cand dadeam drumu la amplificator, sursa se oprea. M-am gandit ca e proiectata sa se opreasca imediat ce simte o crestere brusca de curent.La bateria de la masina merge amplificatorul fara probleme.Asadar, eu zic ca trebuie sa avem grija daca folosim o sursa de calculator, mai ales una mai veche.Eu as avea o alta intrebare referitoare la acest amplificator. Cum trebuie sa fie conectat pinul 16, pentru a functiona la capacitate maxima? In cele 2 scheme pe care le-am gasit, era lasat neconectat. La voi cum e?
