Valy86_86 Posted June 13, 2010 Share Posted June 13, 2010 va salut . am o combina audio samsung si dupa un program mai prelungit pe un canal a inceput sa se auda gajait . celalalt canal functioneaza normal. am desfacut -o si are amplificatorul de putere realizat cu un stk 402- 070 . intrebarea mea , trebuie schimbat integratul sau problema poate fi din alta cauza. mii de multumiri.

remus68 Posted June 13, 2010 Share Posted June 13, 2010 Masoara daca pe iesirea canalului defect ai componenta continua. Link to comment Share on other sites More sharing options...
Valy86_86 Posted June 14, 2010 Author Share Posted June 14, 2010 pe canalul defect scoate 0,6-0,85 v dar si pe celalalt scoate 0.2-0, 6 v si totusi cel din urma nu da nici un semn ca ar fi pe cale de duca. Link to comment Share on other sites More sharing options...

gheo23 Posted June 15, 2010 Share Posted June 15, 2010 Am o amintire tare urata cu o astfel de combina . La timpul respectiv nu am gasit CI original si am facut o adaptare care a mers bine cu un alt STK ( nu mai stiu exact care ) si am avut surpriza ca dupa cateva zile sa pice procesorul . Da ! Finalul este de vina ; cred ca acum s-ar gasi originalul . Link to comment Share on other sites More sharing options...
Valy86_86 Posted June 15, 2010 Author Share Posted June 15, 2010 am inversat boxele , in prima faza si nu asta este problema si nici c.i nu este , ( l-am schimbat si la fel se comporta). cred ca alta e problema dar nu imi dau seama ce ar putea fi . sa fie din preamplificare???
