I like it. The only thing I'd do differently, is add a 9V tap and add one tap that runs through an LM317 with a potentiometer for adjustment. In fact, that's what I did when I built a very similar board for my own lab. That said, this board is much "cleaner" and neater than mine, and I might just buy one or two of these to have around. 🙂
Hi Roger, another source for power supplies is to find old network switches (with built-in power supplies). These often have top brand small PSU's like Delta, CP and Astec. They are usually good for 12v@3a, 5v@3a and -12v@350ma. Most have pots for adjusting the output voltage and the ground is isolated so you can chain them for higher voltages. I have 4 so I ignore the weak minus rails and get ±5, ±12, ±17 and ±24v and all an fit in one deep ATX case with 9 binding posts and no cables.

Damn straight. 2 for a tenner on amazon. Best tenner I've ever spent.
