Schema Amplificator (sa se alimenteze la +-33)

Recommended Posts

nu e corect ce ai spus , prin curent te referi la amperajul suportat de secundar , si la tensiune te referi la volti .... transformatorul tau nu scoate el +-33 V . tensiune cu + si - obtii dupa redresare si filtare, sa inteleg tensiunea indicata de tine este redresata ? , mai exact ce ai masurat tu si de unde stii puterea transformatorului ?


daca ai +-33 redresat te poti juca cu TDA7294 (vezi ca sunt multe posturi cu scheme si discutii , ca sa nu se mai dezbata odata aici iar clasicul 7294)


daca tensiune e de 2 X33 V alternativ redresat urci pe la +-45 V poate mai mult depinde de transformator si filtraj si atunci te poti gandi la http://www.elforum.info/viewtopic.php?t=1 ... sc&start=0
