leaga intrarea la masa si masoara caderea de tensiune pe sarcina ,acesta este offset ulcu intrarea la masa inseriaza cu ambele brate de alimentare (plus si minus)doua miliampermetre si regleaza curentul de mers in gol la 50ma,dupa ce ai facut acest reglaj si introduci semnal da amplificatorul incet si asculta cu atentie sa nu se auda distorsionat,daca se aude distorsionat mareste foarte putin curentul de repaus ,misti foarte putin cursorul semireglabilul,era mai bine daca puneai schema nu cablajul imprimatbafta
