Yap i checked all the diodes.After getting desperate i recall the big force my father who discovered that when i put back the MOSFET Q1 i left behind the heat sink that's why it was short and burning the fuse .How silly i am i know know.Capacitors all checked so probably is ok but i would have to assemble it and test to be sure.Guys you were a great help until now thanks again.I will post back when it will work .
