Problema PROEL PRL 1300


Recommended Posts

Salut, am o problema cu un amplificator PROEL PRL 1300. Merge perfect, dar cand duc volumul dincolo de jumatate, intra protectia, si nu cupleaza din nou releele decat daca reduc volumul pana pe la 25%. Chestia e ca nu am schema lui (din cate mi-am dat seama e un amplificator in clasa G sau H). Finalii sunt MJ 21193 / MJ 21194,(cate 8 perechi pe canal), prefinalii MJE 15030 / MJE 15031. Protectia e cu LM 324N, alimentarea la +/- 90 V.Mi-ar fi de mare ajutor o schema, sau vreo idee care sa ma ajute sa-i dau de capat. Va multumesc mult !!!

Salutare. Va rog daca ma puteti ajuta si pe mine cu o astfel de schema a acestui tip de amplificator? Am un canal care nu functioneaza, mi se ard sigurantele. Am gasit o pereche de MJ-uri arse, eu am MJ15022-MJ15023. Va multumesc anticipat.
