Va cer ajutorul legat de un tranzistor ars .Intr-un amplificator yamaha am 2 tranzistoare C2320, iar dedesubt e trecut 27F. Acestia sunt de forma unui BC , si sunt prinsi pe radiatorul finalilor , banuiesc ca au rol de superdioda sau cum i spune.Problema e ca nu am identic dar am gasit in capsula un pic mai mare, dar nu stiu care sunt buni , avand in vedere ca eu m-am uitat doar la tensiuni, puterea de colector disipata, dar nu stiu legat de Transition frequency (ft): 100MHz , sau la ce ar trebui sa ma uit.Tranzistoarele pe care le am eu suntC2130C2878D863C4408C2655C2235Pot fi acesti tranzistori diferiti sau trebuie neaparat identici, avand in vedere ca unul e bun.Va multumesc.
