  • Quality Components: Custom order NOVER (England brand), EVOX capacitor, DALE Resistor.
  • Extra thick gold plated PCB
  • Applied: For CDP, DAC, Preamp and power amp gain stages modify.

The advantage of the Discrete linear PSU:#

The normal PSU chips have complicated for the best specs on paper, but for human ears, maybe not as good as the specs. Note:
  • The heat sinks have to be connected to GND, so take care while install in the gear.
  • The adjustment resistor can adjust the output voltage, if you have not enough experiences, don't adjust it, we have adjust to standard output before shipment.
  • Connect by wrong will shatter the PSU or the gear.
  • While the PSU working will have some heat.
  • There is better connect the input and GND, check the output voltage if correct as you expect then connect to the circuit.
  • Most circuits have voltage compatibility, so maybe the PSU output voltage have little windage but don't need adjust unless users have enough experiences.
  • Take care the input voltage if make it working over load. If you can't sure the output current, at first hour working attention the heatsink temperature.
