Radioreceptor Gloria cu brum puternic

Recommended Posts

Buna ziua,


in primul rand imi cer scuze pentru ca postez aici, poate am gresit topicul.

As avea nevoie de un pic de ajutor, pentru ca am un aparat Gloria, destul de mult umblat in el, eu asa l-am primit. problema lui este ca are un brum puternic care se aude la volum mic, daca ii dai volumul mai tare se acopera intr-un fel, dar nu-i ok, trebuie reparat.

Am incarcat pe youtube doua mici filmulete cu aparatul pentru nu stiu cat de bine se poate explica problema.


Poate este cineva care ar putea sa inteleaga pe ce parte este problema, pe filtrajul de la alimentarea, la preamplificator, la potentiometru pentru ca si asta imi face probleme pentru ca oscileaza nivelul de sunet.





Multumesc tare mult
