I bought this kit about a year back, when I first started experimenting with electronics. Unfortunately, I put some caps in backwards and they blew up, so I set it aside and used batteries and zener diodes. Recently I found some detailed plans for a dual power supply for a UCSB course ECE 2B taught by Bob York. I was think about building this and then I remembered the kit that I had bought previously, so I decided to salvage the kit instead. I made a few changes through. (1) The kit comes with a "pigtail" fuse. I replaced it with fuse clips. (2) I chose a power cord with a ground and attached the ground to the case of the transformer.

I am not going to give the schematics and such, because this is a commercially available kit.

You didn't attach the schematic, at least draw a block diagram to show how the power wiring, the following is a Power kit that I built it for a long time, because the circuit of board is not my design, so I only shown the diagram and wiring.
