Hi haikel774
                        N-CH IRF740 :400v ,0.48 ohm ,10A {read datasheet}
                        N-CH IRFP460:500V ,0.27 ohm ,20A {read datasheet}


Care must be taken when dealing with mosfet,,,,,,,To change the irf740  by irfp460  must added complete  the circuit of the fet  Between (pin 9 of ic D1B  to GDS of irfp460).
 Of the simplest Care added to FET the heat sink.

 Important Note: to not add a new change to may be  get  a few centimeters !!!!! Because  the main circuit is important,There are many factors in the circuit design are taken into,  and the rest is complemented by the circuit of the fet.

Beware!!!!!!!!!!

best time

j.
