Sziasztok. Adott egy Pioneer xr-p3500 tipusu hi-fi torony, ami nem szolal meg. Odaig eljutottam , hogy az erosito panelen levo dual op amp (upc4570) nem kap tapfeszt. Ezt furcsamod nem a stabkockakrol kapja, hanem egy PAC006 tipusu ic-bol. Ebbe megy be a mute fesz is ami 4,6v, tehat nincs aktivalva a mute funkcio. Megis a +-12v-ot szolgaltato labakon 0 v van. Amit meg eszrevettem: a -12v-os stabkocka kimeneten csak -9,5v van. Ez egyben a PAC006 ic negativ tapfesze is. Lehet ez a problema?
Üdv.
Keresem a fenti deck mechanikájának a robbantott rajzát, ha megvan valakinek, legyen szíves küldje el.
A hibája, az egyik irányban nem emeli fel a fejszerelvényt teljesen.
