ma poate ajuta cineva cu o schema de amplificator Audison?mentionez ca nu stiu ce fel de model este, nu scrie pe el dar are sursa diferentiala de tensiune obtinuta din cei 12v, nu am alimentare pe amplificatoarele iar sursa are mai multe integrate. va rog, macar niste idei, in sursa se afla LM393P, SG3525AN si altele care nu pot citi ce tip sint.

multumesc pentru promptitudine, acesta este amplificatorul, fara schema sint in pom, sursa creeaza doua tensiuni de alimentare de +, - 23 v, alimentare diferentiala, dupa punerea in functiune la aproximativ 5 sec. dispare tensiunea de -23v, ramine in schimb cea de +23v, mai jos este foto a amplificatorului.imi pare rau nu stiu sa bag foto, nu este acela amplificatorul.
