Transient Modules u3A DIY build manual - Version 1.1
1. Empty the bag into a bowl or
container. This makes it much easier to
pick the parts as you need them and
you're a lot less likely to lose anything.
2. Let's start with the SMD parts! Solder
the 2x TL074 ICs. Position them with the
line on the top face
of the TL074 at the
same end as the circle (pin1) in the
silkscreen, as shown in the image.

TIP for SMD soldering:
3. Solder the 17x 10K resistors.
Colour code: brown, black, black, red, brown.
4. Solder the 2x 1N4007 diodes.
NOTE! Orientation is vital. The gray line
on the diode (cathode) must match the
silkscreen, as shown in the picture.
5. Solder the 2x ferrite beads
.
6. Solder the 7805 regulator. Labelled
7805.
7. Solder the 7x 100nF capacitors,
labelled 104.
There are 2 capacitors that have a more narrow
space between legs than the others. Those are
for the top board!
