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:
      1, The heat sinks have connected to GND, so take care while install in the gear.
         2, 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.
         3, Connect by wrong will shatter the PSU or the gear.
         4, While the PSU working will have some heat .
         5, There is better connect the input and GND , check the output voltage if correct as you expect then connect to the circuit .
        6, Most circuits have voltage compatibility , so maybe the PSU output voltage have little windage but don't need adjust unless users have enough experiences.
        7, 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 .
