casetofon deck SONY TC-K2A sunet distorsionat

Recommended Posts

Asa cum am specificat in titlu, sunetul redat pe ambele canale este distorsionat si infundat, fara acuratete

Tensiunile de alimentare corespund schemei(exista la documentatie un topic deschis de mine)

Am incercat alimentarea cu 10v din sursa externa, dar nu este nicio modificare

circuitele de tip 4558 sunt ok, nu stiu de unde provine defectul, aparatul arata impecabil

ce sfaturi i-mi dati?

Capul de redare este in regula? Niste poze ar fi binevenite.

Pe placa amplificatorului de redare trebuie sa existe un switch de tip glisant (ptr PB-REC) -din ce vad in schema . Acolo cred ca este problema (contactele argintate din interior oxideaza in timp), ar trebui desfacut si curatat. Cu un osciloscop se poate depista rapid cauza, urmarind calea de semnal.

Cateva picaturi de motorina in comutatorul Rec/Play,concomitent cu manevrarea energica a acestuia,si aparatul va functiona ca nou!Satisfactie garantata!
