Instructions

Sort and lay out all parts:
Bend the resistor just enough so that it can be
passed through the soldering lands.
Push the resistor leads through the circuit
board (from the labeled side)
Solder on the diode and
shorten the protruding
wires to 1 mm.
Solder on 220 nF capacitor and trim
protruding wires.
Solder on IC socket. Shorten protruding wires to 1 mm.
Solder 150 nF capacitors and
shorten protruding wires to 1 mm.
Solder the resistor leads and shorten protruding
wires to a length of approx 1mm above the solder
point using side cutters.
With the resistor,
you don't have to
pay attention to
the polarity.
With these capacitors you do not have
to pay attention to polarity.
Ensure that
you have the
correct value!
With this capacitor you do not have to pay
attention to polarity.
With the IC socket pay attention to polarity!
With the diode you have to
pay attention to the polarity!
