Complete a power supply board, in fact, is one hour should be completed.Best of U1 & U2 plus an IC socket, can be conversion IC. Power of up to 2A is no problem. Addition Q8 & Q10 can change transistor, if you want more A, can be put on a 2SA1943/2SC5200 of, but at the same time increase the transformer VA.
