Precizati care e tensiunea de alimentare in gol,si ce finali (par a fi npn ) are.
Asa,"ochiometric",ar fi suficienti bd241/242;finalul e in clasa B ,fara curent de repaus-are doar 2 diode la bias.

Verificati componentele din zona finalului,componentele active ,circuitul de protectie ,rezistentele din baza prefinalilor si condensatorii ceramici;amplificatorul e pentru sonorizare,fara performante deosebite

Am gasit un 2n3055 si tranzistorii din protectie copti. Tensiunea e 2x35vcc, finalii sunt ambii 2n3055. Amplificatorul e mono, are si traf de iesire.

Scosu' schemei de ceva vreme ma gandesc sa o fac, da am o lene si un chef de nimic zilele astea...  hungover_40_anim_gif.gif
