Sziasztok.
A fentnevezett rádiót nemrég hibásan kaptam.
A Tanyán található Kenwood KR-A47 rajz alapján,sikerült megjavítani,hiányzott a +14V.
A rajz nem pontosan ezé a rádióé, de az erősítő és a táp ugyan az.
Szépen szól az erősítő, és a rádió jó érzékenységű szerkezet.
Egyetlen hibája hogy kikapcsolás után, kb. egy óra hosszáig tartja meg a memóriába beállított frekvenciákat.
Mivel elemet vagy akkut sem a rajzon sem a rádióban nem találtam,kapacitását elveszített kondenzátorra gondolok,de nem tudom melyik lehet.
Ebben kérném hozzáértők segítségét.
Előre is köszönöm.
Laci.
Sziasztok!
Thomson DPL 580HT tip. erősítő st.by-ból bekapcsol távval és előlapról is. Tápok rendben, st.by-ban van clock és data-jel, de bekapcsoláskor eltűnik, csak "szőr" van helyette. A proc. oszc-a sem él. A kijelző is sötét, és onnan már természetesen kikapcsolni sem lehet.Van valakinek ötlete?
Köszönöm
Attila
