Hello, in a switching power supply unit there is 2SK1189 broken mosfet.
A cross reference give me BUZ51 as possible substitute.
I have a P6NA80 ... could I replace the 2sk1189 with this last one?
Yes, the original part is 2SK1199 ... sorry for typo.
In attachement there is the PSU schematic where I have to substitute Q1 (and some open resistors).
