Rotel RA 1570
#15
Hmmmm, počeo da sklapam posle promenjenih delova, nije ih bilo puno, 2 tranzistora (ksa992f i ksc1845f) i par otpornika u OT i OL kolu. Prvo paljenje preko sijalice na primaru....,stand by relej se pali i gasi otprilike 2 puta u sekundi. Naravno sve sam konektovao ponovo kako je bilo. Posle toga sam povadio osigurače glavnog napajanja za snagaša i preamp je proradio ali i dalje mi na displeju kaže da je aktivirana zaštita zvučnika.
Gledam šemu i nije mi jasno, OL, OT kolo se napaja iz glavnog napajanja kao i uPC1237 preko 18k otpornika koji sada nisu aktivni jer nema napajanja. Otkačim konekciju CP/CN608 - sve ok, nema više greške. Mene interesuje kako prijavljuje grešku ako nije pod naponom. Naravno, prikačeni 8R dummy load na oba kanala.
Ono što nisam promenio na tom jednom kanalu u OT/OL su 1N4148,sad ću sve da raskupusam ponovo pa i to da proverim mada ne verujem da bez napajanja bi zbog njih prijavljivao grešku.
Devojka me vara sa rođenim mužem!
