as avea nevoie de o schema pt un amplificator auto mtx x1000d. L-am mai reparat acum un an jumate, dar atunci am scapat cu un ir2184, un lm393 si doi tranzistori pe sursa. acum se comporta prea ciudat si nu pot identifica tranzistorii smd de pe driver-ul audio.plus ca e in clasa d si nu am chef de prea multa joaca.

Acel condensator nepolarizat de pe iesire era electrolitic nepolarizat?Ce prostii mai fac si unii producatori, acolo trebuie un condensator serios cu polipropilena sau poliester, electroliticii nepolarizati de 10uf au viata scurta in conditiile acelea pentru ca li se depaseste cu mult curentul maxim de riplu
