Default Behringer europower pmh1000 blown psu

Hi all. I have a question about this mixer. The psu has blown and I was wondering if anyone know likely components that go. I know its a longshot but am sure their must be some engineers out there that fix them. I am an electronics engineer myself so am pretty competent when it comes to these things, but frankly, switchmodes are a bastard even with a schem so without one I def need help! anyway, the 2 cool mos transistors (17n80c3) which im assuming are the primary side chopping transistors have blown. This has also taken out R58,R59,R67,R68 surface mount. cant quite make out value but think is .47 or 47 ohms and are connected from -o/p of bridge rect to the top221p mosfet pwm controller. Also gone are R34,R43 and C7. These are just the smd's that have obviously blown by looking at them. I havent got down to checking other things with ohmeter/diode checker yet. Am I wasting my time or does anyone know if this is a classic chain of components that goes and what else should be changed?
would really appreciate any help. thanks
