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.


Optional Upgrade:

  • Furutech NCF IEC Socket for ultimate power contact performance
  • AfterDark. AudiophileMAT Carbon Fiber for EXTREME EMI Shielding
  • AfterDark. Project ClayX Progressive Carbon Fiber Shielding (CFS) Duelund DC power cable
