Hy, it doesn't have the service diagram for my power supply model, it is diffrent. I can't find: Q102, R131, R132, R133, R134, R139, C113. These pieces were charred, and can not be identified.

I have the same problems with the R131 to R133. I think they are 0.200ohms from the markings but you might put in a single higher wattage leaded 0.47ohm resistor to replace all four surface mount units. Later, you can put another in perallel to up the power output. The transistor is a 600V 6A N-channel mosfet made by SGS called STP6NK60ZFP. The "FP" is a version of the TO-220 package where none of the three terminals is electrically connected to the heat tab. To get an idea of the circuit, you can take a look at page 5 of this **broken link removed**

Good Luck
