DIY Power Supply

I currently work on a DIY Power Supply which has 2 regulated Outputs (each 1-40VDC @1A) and a 5VDC/2A fixed Output. I am thinking of adding a 12VDC output later.

I decided to make it myself, because its cheaper and i can design it the way i want it to be.

For the regulated outputs i use 2 LM317 regulator circuits, each on an own 30VAC/1.3A coil from the transformer. The 5V are supplied directly from a 230VAC to 5VDC switching converter.
