HiFi Walt Jung Super Regulator DC Power Supply Board Linear PSU Audio DAC Preamp

Description

HiFi Walt Jung Super Regulator DC Power Supply Board Linear PSU Audio DAC Preamp
Wide DC output range from +-5V to +-18V (AC input from 7V to 18V)
Circuit is refer to  Walt Jung's design, He has been
designing DC regulator since 1961
Extremely low noise, Also very low output impedance, ideal for preamp/ DAC or other high audio purpose. It should be one of the best in today's discrete (All discrete) regulators.
Don't use a simple three-terminal LDO. The experimental results tell us that this is not an opponent at all. Regardless of the communication, response, and impedance, SJR can be said to be a big win.
