Hello, I got the converters damaged, the symptom was this after putting the power supply 24 in the car under the cigarette lighter, the fuse burned immediately I do not know much about electronics, after soldering the ssf 7509 transistor it has a short circuit in all directions, the question is because there are two next to each other the same, Can I insert another transistor or it must be the same, thank you ....... 
Added after 5 [hours] 22 [minutes]:
I decided to replace this transistor with 60NF06, I do not have a 24v battery, but I connected a rectifier bridge and a 4000uf capacitor to the transformer, I got a voltage of 22volt, but after connecting the inverter, the green and red LED lights up and no voltage 230v on the output, advise .......

Maybe the diagram will be dropped off by someone .....
