Üdvözlöm a Szakikat!
Kaptam egy retro Sokol 308-t.A javítással annyira jutottam,hogy gyanús lett a "Z" jelő szűrő (L7 szekunderében), kivéve megy az AM. Valami adat kellene erről a szűrőről.Az AGC felőli kimenet és a föld között 8 kohm ellenállást mérek.Minden segítséget előre köszönök.
I Have a Sony STR-V55 stereo receiver and need a relay for it. It is 24 volt and the Soney part number is 1-515-347-00. RY801 on the schematic. Can anyone give me an idea how to cross reference the Sony part number? I am not having much luck finding it on line.
Thanks
Sziasztok!
Nevezett erősítő került hozzám, tápegység hibával. Nemrég járt szervizben, de pár hét után ismét megadta magát. Láthatólag két alkatrészt cseréltek benne: R419/D405
Most ugyanez az ellenállás égett szét. A zener jó, viszont nem tudom az eredeti jelölése mit takarhat. Helyette Z10M lett berakva (ez sem sokat mond)
Jó lenne konkrétan tudni, mik lehettek, mert addig nem látom értelmét továbblépni és a tönkremenetel okát keresni.
Üdv,Z.
Van egy Onkyo TX-NR509 erősítő. A hiba jelenség: bekapcsolásnál a Check SP Wire hibaüzenet jelenik meg, szinte egy pillanatig, majd utána kikapcsol. Kérnék egy kis segítséget a hiba behatárolásához.
