I am trying to bend a really simple keyboard, but I can't get it to stay powered up. It will run for 3-5 seconds, then shuts down. Powers right back up, then shuts down, any ideas what component is failing here?

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

It's the johnson regulator. Oh, and the T-valve... most definately the T-valve.
