Buna ziua , stiu ca nu sunt total in topic dar nu stiu unde altundeva as putea posta.

Are cineva schema electronica a mudulului preamplificator pentru magnetofonul Orbita MPK 108C mai exact pe unul din canale la un sunet mai puternic sau o variatie de tensiune(de exemplu cind comuti pe alta turatie) preamplificatorul intra in auto oscilatie si pina nu decuplezi modulul de pe placa de legatura nu-si revine chiar daca scoti magnetofonul din priza si-l pornesti la loc. Condensatorii electrolitici au fost schimbati primii , banuiala cade pe unul din cele 3 IC-uri

​k547kp1a (am folosit caractere latine , denumirea reala a circuitului i rusa este К547КПA), eventual imi puteti indica de unde se pot cumpara acest  circuit ?

 

Multumesc anticipat,

Calin Bradateanu
