Sherman, thanks to schematic, i'll do it that way but i have a question;
AC1 and AC2 (from the transformer) are our hot wires, aren't they? why we don't wire AC1 to AC1H, AC2 to AC2H and then CT to both AC1N and AC2N?

If you use two bridges and have twin secondaries, you load the transformer better so can get a little more current out of it for the same temperature.

Also, it's better from a grounding perspective as when the top half circulates current it does not travel in the same ground loop as the bottom half, and the star ground really is only at the centre point of the smoothing caps. With a single bridge or centre tapped transformer, the star point is shared between the caps and the tap, so the length of this connection is important/influential.

I modified my center-tapped transformer in order to have twin secondaries, is it better to wire one secondary out of phase anyway???
