Üdv!
MACKIE SRM650
Tápegységének javításhoz kérnék segítséget!
PCB_ LFPA_02490-0001
PWM_vezérlő L6599AD
kapcsoló fetek 4db G20N50C
kimenő villanyok: +-50V, +-15V +8V
A gondom, hogy instabil a kimenő fesz, / +-15V, illetve a +8V/
A +-50V nál a pufferek csúcsra töltve. / terhelés hatására lebeg/
Az egész panel fehér szilikon pasztával telehányva!!!
Forrasztási oldalról a kondikat ESR mérővel ellenőriztem.
Az SRM 450-é még véletlen sem hasonlít rá, egész más kapcsolás.
Csak ott bontanám meg a szilikont, ahol a hiba gyanítható!
Esetleg manuálét tudnátok a prezentálni? Akár meg is vásárolom!
Köszi Pozsgai
Sziasztok!

Üdv SuPeti
Sziasztok
Van egy Sony cd játszó aminek sajnos nem lelni a rajzát sehol és a 591-es abszolut más belvilágú. Sajnos nem forgatja a lemezt a motor meg jó. a lézer próbálkozik. a motort egy LA6520 ic hajtja. Tud valaki ajánlani egy másik típust amiben szintén ez az ic dolgozik, hogy megnézhessem a vezérlés módját. Az ic adatlapja már megvan.
Köszönöm Laci
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.
