sunt aproximativ echivalente. diferenta este ca 6n tine 6 amperi. foloseste-l macar pentru teste, dar inainte sa-l montezi, masoara rezistenta sau rezistentele dintre sursa trz si masa, dioda si rezistenta din poarta, puntea redresoare si condul de filtraj precum si eventuale alte componente conectate la acest tranzistor. daca se incalzeste prea tare, maresti radiatorul sau schimbi tranzistorul cu 9nk60zfp (9 amperi/600volti). deasemenea se recomanda schimbarea tuturor condensatorilor electrolitici atat din primarul cat si din secundarul sursei. faci proba cu bec conectat in locul sigurantei de pe 220v.
