Sziasztok!
Keresem az europhon rck 1540 régi music-center rádiórészének kapcsolási rajzát.Hibás az fm része.
Először antennával volt teljesen érzéketlen,az első tranzisztor lábához érve halkan szólt.Szétszedtem, az első 3 tranzisztort kicseréltem újra, mindent átforrasztottam.A rádió am-fm része 4 tranzisztor+tda1220ic.Most antennával vannak állomások kis hangerővel közte hangosan sistereg,a sáv végefele egy két adó zajosan és hangosan szól.Mi lehet a baj? Lefényképeztem a panelt. Amire jutottam:
Ha egy másik zsebrádio kf jelét rákötöm a KF szűrőre akkor is olyan hangerőn (kb negyedhangerő) szól, mint a saját hangolásával, de ha félrehangolom, vagy nem kötöm rá az antennát, csak közelitem, akkor nagy hangerővel csak sisteregve, torzan szól.Lehet, hogy a tda TDA 1220 ic IC hibája?
Sziasztok!
Europhon TA-88 és erősítőjéhez keresek leírást, információt, bármit.
Köszönettel:Csaba
