Buongiorno. L'amplificatore come da titolo inserendo un segnale dai rispettivi ingressi in uscita non si sente nessun suono. Le tensioni allo stadio finale, servite da transistori sono corrette. ho notato che anche nella cuffia non si sente l'audio. Potreste per favore darmi qualche suggerimento in merito? Grazie.
Sziasztok!
Most került a kezembe ez az erősítő, szétszedve kiderült hogy megszakadt a 5A-res bizti. Átmérve minden végfok tranzisztor jó, de nem indul el a táp része, vagyis hiányzik a +-25V. Most átmérve a meghajtó tranzisztorait, hibásat nem találtam, most a HD7402P icére gyanakszom, de nem találtam beszerzési helyet itthon. Valaki tudna segíteni, hogy tönkre szoktak menni? Ha igen akkor meg mivel lehet helyettesíteni?
Sziasztok!
PIONEER A303R erősítő hangerőszabályozójának cseréjével kapcsolatban vannak kérdéseim.
Mielőtt szétbontom,próbálok tájékozódni!
A hangerőszabályozó egység "poti" vagy enkóder,vagy egyéb?
Javított ilyet valaki?
A "VOLUME" egység típusa? (A panelen AWZ 5546 felíratot látok,de lehet,hogy csak alkatrész pozició szám)
Üdv. Ottó
Tisztelt fórumozók!
A fenti autórádióval volna problémám, éspedig az, hogy bekapcsol, tökéletesen kijelez mindent, de hangja nincsen.
A végfok jó, a PM9013 vol Ic bemenetén van jel, a kimenetén semmi.Megköszönném, ha valaki segítene!
