Si o schema clasica si simpla de amplificator audio:

 

Numai Bine

[victor postolachi]

iata am postat si io o schema ,in curind ma apuc so fac , rog specialistii sa dea o parere, va rog mult!!!!!!

multumesc!!!!!!!!!!

itzi las eu o schema simpla ................cu un tda8560Q............personal am realizat acest amplif shi vreau sa spun ca merge foarte bn.......iar alimentarea potzi sa o iei dintr-o sursa de Pc.........schema o gasesti la pagina 10 a pdf-ului

TDA8560Q.pdf

Un amplificator foarte simplu

[ImiDj]

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.

Ma poate ajuta cineva cu o schema de FISHER CA 863 - multumesc anticipat.

 

EU ACU O FAC PE ACEASTA unul deja e vindut puterea nominala 220w max 330

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.
