Sziasztok
Lorta (Amfiton klon) órosz erositoben egyik oldalaban kimentek a veg es a meghajto tranzisztorok, kicsereltem oket, de most teljes hangerovel búg, a zene pedig alig fellelheto benne.De ez mindkét oldalon!
Tápja jó: +/-33V. Probara tapelko csere, gretz csere tovabbra is búg. A javitott oldalon minden kiselkót cseréltem.Tranzisztorok nem melegszenek.
A bemeneti koax kabel halojan keresztul kapja a 0-at! (kábelspórolás?), ha ezt kicinezem a vedelem nem kapcsolja relen keresztul a hangszorokat.
Ha csak a koax belsojet cinezem ki akkor is bug.
Ha pincettaval hozzaerek az egyik TO-92-es tranzisztor kolektorahoz, egeszen elhalkul a bugas, de viszont errol a labrol csak 1 db ellenallas megy tovabb, de az ellenallas masik labanal mar nem halkul el a bugas.
Más: Eloerosito potira (tobbfokozatú ellenallaskapcsoló) nem reagal a hangerô, de szerintem ez mar masik problema.
Na akkor most akkor mi baja lehet?
