Amplificator 2 x 150W "la vedere"

Recommended Posts

Salutare stimati colegi!

Va prezint un amplificator cu TDA7294 Bridge ( nimic nou sub soare ), este un amplificator de buget foarte redus cu performante decente pt cat a costat producerea lui.

 

Amplificatorul e facut cu 2 kituri cu TDA7294 in bridge, 4 transformatoare de iesire ( 115V /11V @ 150W) folosite in serie, radiator de la un amplificator auto, pornirea se face prin relee pt a nu aduce tensiunea de retea pana in partea frontala a amplificatorului.

 

Amplificatorul a fost botezat CM300.

Trafurile de iesire au fost reutilizate pe post de trafo de retea. Asa inteleg din descriere.

Ok ........mi-era teama sa nu fi inteles eu altceva ....

 

Si totusi de ce ??? te-ai complicat cu inserierea traf-urilor de iesire cand puteai folosii un singur traf sau ma rog cel mult 2 daca vroiai un dual monobloc

Pt ca le aveam , le tineam degeaba si in alta aplicatie nu prea aveam unde sa le folosescSa nu mai zic ca pretul lor a fost o nimica toata.

Si eu care credeam ca nu intamplator le-ai alimentat in stilul kenwood din thx-1000...
