comparatie intre amplificatoare

Recommended Posts

Am si o intrebare.Am facut si io cateva amplificatoare (sunt incepator ) nu multe si ultima mea realizare a fost un ipa60 cu irf930/530 la +/30V si putere de 50-60W nu am masurat (sunt prea multumit de calitatea sunetului nu ma mai intereseaza puterea )Vreau o comparatie intre :1) Ipa 602)Lm38863)Tda 72944)Tda 1562 Io as opta pt ipa60 si ca bani si calitate

Circuitele integrate in tehnologie monolitica gen TDA, LM etc...sunt slabe, ca sa nu spun extrem de slabe. Eu unul prefer varianta cu tranzistoare bipolare pt obtinerea unor puteri mari modulate pe impedante de difuzor de circa 2- 16 Ohmi. Tranzistoarele MOS-FET sunt si ele bune dar nu pt obtinerea unor puterii mari debitate de amplificator.

dar pe cine ai pune pe locul I dintre toate astea luand in considerare puterea/TDH

as pune lm3886.Nu neaparat ca performante, dar pt protectiile ce le are implementate si usurinta cu care se face montajul.
