    I came up with these awhile back; both could be run off the same 20v-36v unregulated supply. Both are rated for 2.5A; could go to 5A by changing the regulators to LT1170's. Pretty simple. You can add meters if you wish.

    In the 2nd schematic, L3 is optional - but helps considerably with the power dissipation in R5. Without it, R5 will dissipate around 1W.
