alimentare Grundig V1000


Recommended Posts


Ce parere aveti despre pozitionarea sigurantelor 701 si 702 ?

Eu cred ca este f misto schema, deoarece:

1-daca se arde una din sigurante, redresorul se transforma din bialternanta in monoalternanta;

2-daca defectul persista se arde si cealalta siguranta;

3-ampliful nu ramane alimentat doar intr-o ramura (+ sau-).

Astept parerile voastre.

O alta idee draguta, este montarea celor 4 rezistente din emiterii tranzistorilor finali, pe ac. radiator cu acestia si superdiodele (este stereo). Pe radiator este montat un releu termic, care intrerupe alimentarea primarului trafo retea. 

Sunt protejate termic transformatorul (118+/-6 gradeC), cat si etajele finale (100+/-4 gradeC).
