Looks different.... Shouldnt you connect your "virtual center taps" from the Toroids to the Gnd instead of creating a Quad like gnd from the main caps?

basically the "D" of Toroid 1 will be connected to the "A" of Toroid 2 to make your center tap or gnd....

D
 
Trannies OK, bridges wrong

The transformer wiring looks ok to me (as long as you really are planning to use two bridge rectifires, not one) , but I think you have the bridge rectifiers wired incorretly.

The negative of the top bridge should connect to the positive of the bottom bridge.....

that's all
