Amplificator Kenwood A54 cu ceva probleme

Recommended Posts

Guest George Pataki

Salutare, am un amplificator Kenwood A54 fabricat la inceputul anilor 2000. Am ceva probleme cu el si nu stiu de unde sa o apuc. El merge binisor dar doar pe un singur input - CD direct. Deci problemele are fi urmatoarele:

- in afara de CD direct celelalte intrari (AUX, TUNER, TAPE IN, CD simplu) sunt moarte, nu duc semnal in preamp.

- canalul dreapta are volum sensibil mai scazut decat stanga (atat pe A cat si pe B).

 

Ca si electronica stiu bazele, dar nu am aparate gen osciloscop, etc.

Daca simptomele vi se pare "grave" si e cazul de cineva cu multa experienta va rog sa recomandati. 

 

Orice idee este apreciata. Multumesc

Posibil IC3 TC9164 defect ptr intrări, iar ptr volum diferit pot fi cîţiva cond electrolitici în calea de semnal.

Multumesc pentru sfaturi. In cazul in care nu reusesc am nevoie de o recomandare, un coleg mai experimentat care sa il reperare. De preferinta in sectorul 3/Titan.

Puneti foto cu mufele din spate.Am avut si eu un astfel de amplificator si problema era din doua mufe care sunt cu iesire semnal de la AUX, TAPE, CD,TUNER si unele cu intrare in amplificatorele audio. Practic acolo erau niste strapuri (care lipseau) sau se putea trece semnalul audio printr-un egelizator folosind cabluri RCA.
