Plug in the power supply, and then test us
Touch the black probe on the GND test point and the red probe on
the 5V test point. The voltage should measure between 5.
Volts. If not, disconnect power and check your work. Do not
proceed with the assembly until the error is corrected.
Once the test is completed, disconnect the power.

R2 (390 KΩ)
Q1 (IRFD220)
D4 (UF4004)

Socket for IC2
Pay attention to mount
PCB marking. Insert the 28 way IC socket into the PCB at the IC2
position, ensuring that the notch at one end is aligned with the
corresponding marking on the PCB.
C4 and L1 are soldered on the opposite side of the
components. The white PCB marking will guide you.
Note that L1 will be one of three possible types.
If your L1 is the type with the longer wires, you will need to bend
the wires over so the part is soldered laying on the PCB, as ma
on the PCB. Otherwise install the component conventionally.
