The Heart of AfterDark. Black Modernize Linear Power Supply

The circuit design of LPS is referenced and improved of the well-known Walt Jung Super Reg. The performance is first in the class I must say. Output voltage stays VERY stable with 0.01VDC tolerance despite I'm driving it almost at full load. It only gets a bit warm after a 48hrs of stress test.
