Montezi un preamplificator...Cred ca tda1524 merge ok..parca scoate cat iti trebuie tie....dar cam are zgomot de fond mare....sau daca nu vrei corectii de ton si volum un operational e cea mai buna solutie ...

Uite o schema speciala pentru tine fara inversare si cu gain reglabil de la 1 la 5Poti incerca si tda2320 sa vezi cum suna..dar tot cam asa trebuie sa faci montajul..oricum condensatori la intrare si iesire sunt obligatorii...
