Next up: inserting & soldering the transis-
tor.
Make sure you align the transistor with
the marked outline on the silkscreen – orien-
tation is critically important here . Also,
insert film capacitors and solder them.
Then complete the component side of the
Envelope PCB by soldering the
PSU socket.
Make sure the orientation of the socket is as
shown in the picture below – the arrow point-
ing to the first pin is aligned with a notch on
the silkscreen. The key on the socket will be
facing inwards towards the PCB . Now your
PCB should look like this:
Now, turn the PCB around and inspect your
solder joints.
Make sure all components
are soldered properly and there are no
cold solder joints or accidental shorts.
Clean the PCB to remove extra flux, if neces-
sary.
