Un amplificator pe care le-am construit si sunt foarte multumit de el.Finalele se poate schimba cu MJ15003-MJ15004 si prefinalele cu bd237-bd238.Suporta lejer +-45v.Este un amplificator simplu de tranzistoare.

Nu l-am realizat, este din rev Tehnium martie 2005. 2X20W este mai mult decat suficient pt o sufragerie.

 

Iata si PCB Dimens pcb=100/65mm.Scuze pt calitate,nu am scaner.
