Va salut,

Va rog sa ma ajutati cu urmatoarea problema. Am un amplificator de semnal FM pentru masina la care firele au "plecat" si nu sunt sigur acum ce si unde vine.

Nelamurirea principala este unde vine alimentarea(+12V) si iesirea de semnal.

Ce am identificat, corect cred eu, este:

-masa(firul rosu). Stiu.. e rosu :) o sa-l schimb.

- intrare semnal, firul galben.

Acum banuiala mea e ca pe firul negru ar veni +12 V(o sa-l schimb cu culoarea potrivita) si iesirea de semnal ar fi la condensatorul de langa bobina cu miez de ferita.

Va rog sa-mi spuneti daca e corecta banuiala mea.

Poza cu carcasa e luata de pe net. A mea e la fel insa nu are modelul scris pe ea.

Multumesc

Cu mare probabilitate ,acolo venea un cablu ecranat,,gaura de alaturi merge la masa-ecran,,cel mai sigur-identificati trz.din stanga,vedeti dispunerea pinilor si daca R siC ce duc la gaura indicata ies dintr-un colector aveti iesirea,daca dintr-o baza aveti intrarea.
