Am nevoie sa trezesc la viata niste incinte amarate, am un amplif cu un TDA de vreo 2x15W si am gasit si un corector cu respectivul NE5532.problema e ca nu vreau sa caut transformatoare si alte nebunii, amplif-ul merge la 12v iar corectorul la +-12 sau ceva de genu.intrebarea e: pot alimenta corectorul de la o sursa de pc? avand in vedere ca da +-12v, problema fiind ca pe -12v doar 0,5A dar la cat consuma jucaria asta...deci? merge sau nu?danke

Merge , numai sa ai grija ca pe Vcc si Vdd sa plasezi niste filtre simple LC pentru ca sursa PC este putin cam zgomotoasa (L=10microH-..cat mai mare, eventual recuperate din TV etc , C=100nF de exemplu).
