transformator de iesire?


Recommended Posts

Buna ziua

 

Am intrat recent in posesia a niste transformatoare facute de sanyo. Am primit ca fiind trafuri de iesire audio din tv cu lampi.Am doar codul de pe trafuri fara sa stiu si altceva despre ele. Sunt interesat de impedanta lor, pt o eventuala refolosire. Trafurile sunt impregnate cu ceara.

 

Codurile: T-V108

T-W51

T-W23.

 

Si tot cu aceasta ocazia as mai interesa de un traf cu codul 9WN 676 09

Multumesc de ajutor

Impedanta de intrare poate fi de 7 kiloohmi, iar cea de iesire, functie de difuzor, 4 sau 8 ohmi. Raportul de transformare se poate masura la 50 Hz, iar patratul acestui raport reprezinta raportul impedantelor. Orice pentoda finala uzuala (EL 84, etc.) poate folosi acest transformator fara probleme.
