In asteptarea raspunsurilor de la cei experimentati in domeniul audio, imi dau si eu cu parerea, dupa ce m-am uitat pe foile tehnice ale tranzistorilor.

S9014 : http://pdf1.alldatasheet.com/datasheet- ... S9014.html

Este un tranzistor dedicat in preamplificare, cu zgomot redus si linearitate a hFE.

 

BC547 : http://www.play.com.br/datasheet/BC547.pdf

Nu se poate lauda cu zgomot redus. Din familia lui, BC549 are zgomot redus dar are tensiune de functionare cu mult mai mica decat S9014.

 

Parerea mea este ca nu prea merge inlocuit cum vrei tu.
