Probabil ca R5 sau C2 sunt decalibrate. De obicei la astea de 2X50W asa se intampla. :partyman:

Totusi nu inteleg de ce este legat la iesirea amplifului cand trebuia pus la + (plus) sau la o tensiune mai mare de 8,5 volti (consulta datasheetul)

probabil s-a mai discutat si pe forum astfel de subiecte... oricum e bine sa consulti datasheeturile circuitelor inainte sa te apuci de lucru...Stiu producatorii ce zic acolo ca doar nu fac alea degeaba doar asa ca sa se afle in treaba...

A mai aparut ceva asemanator in tehnium in numarul 5.99 pun pagina scanata aici poate te intereseaza... Acea schema pare interesanta insa nu stiu cat de bine functioneaza(daca functioneaza)
