Amplificator Vlliodor DS 9702


Recommended Posts

Putere  2x500w  a avut un canal ars am inlocuit cei 4 tranzistori finali  2buc  2SA 1295 (10lei) si 2buc 2SC 3264 (21lei).

Deasemenea au fost arsi si prefinali  A1837 ,D669A ,D667 , B647 si mai multe rezistente de valori mici .

Am verificat toate diodele am inlocuit toti tranzistorii arsi si am alimentat amplificatorul a mers 5secunde corect si a topit doua rezistente ,sa ars si cei patru tranzistori finali  precum si alte rezistente.

Mentionez ca celalat canal functioneaza corect .

Oare de ce sa ars din nou asa de repede!!?
