Dude, I am assuming you want to put it all together, right?
It is a very simple circuit - you need to post a large picture of both sides of the board and someone can point you in a right direction.
I see a rectifier bridge in a center of it - so that's where you want to connect your transformer 2x24 outputs. The outputs are where you got these large transistors - and the inputs are the small blue screw connectors. OK?
