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.
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
