Ce am primit de la scormonel tocmai le am.D-le zal,ce parere aveti,merita facut sau sa pun inapoi in sertar ude sta de citiva ani buni.Si eu am inceput sa cred ca 7294 e mult mai bun si mai usor de realizat.

Ptr 25W sinus nu prea merit?, singurul avantaj fa?? de TDA7294 e talpa mare ptr r?cire, în rest sînt echivalente cînd sînt alimentate la tensiuni egale (de regul? +/-33V). E bun la o depanare, atît.

Iat? cîteva scheme reale cu STK-ul respectiv, sau altele din familia lui. Aten?ie c? schemele din pdf-ul de mai sus sînt scheme de principiu, nu unele func?ionale, a?a ceva se g?se?te numai în amplifuri vîndute pe pia??, la vremea lor. Scuze ptr calitatea pozelor ?i desenelor, sînt scoase din amplifuri reparate cu mul?i ani în urm?. :limb:
