Remove one rectifier bridge, you don't need it. It's already rated for 35A. The input of the bridge (~ or AC) goes to the outside taps of the trafo, the (-) of the brigde goes to the -Vcc. Center tap of the trafo is the GND. But if your purpose is to parallel the bridges, that's OK, mali lang ata connection ng diodes. Dapat (+) to (+), (-) to (-).
Hindi dapat naka-series yung 104 cap sa 100uF cap.
