Nu trebuie sa deschizi doua posturi pentru a-ti expune problema.

Daca nu ai apucat sa scrii tot, exista butonul edit.

Mutat de la "amplificatoare" EDIT - sorteh.

sursa ta de alimentare, din amplificator, a fost gandita pt a servi amplificator ce e in prezent folosit ... asadar, pt a mari puterea amplificatorului nu e deajuns sa schimbi tranzistorii cu alti de putere mai mare .. trebuie intervenit si in partea prefinala a amplificarii, si in sursa, si cel mai probabil vor trebui marite si radiatoarele (carcasa), asa ca ... nu se prea merita :yawinkle:
