Please read the notes on soldering Poor soldering is the most common cause of a kit failing to work first
time, so please take the soldering advice at heart! Once soldered cut off the excess length of the part
lead as close to the joint as possible. Install all resistors from the parts list and carry on until all resistors
are soldered in place.
Values which are in decade increments may be easily confused, such as 470, 4K7 and 47K. So, take a
good look at the colors before you solder the part in place! In case of doubt, use a multimeter to check
the resistor value.
R2 is an SMD resistor, factory installed.
Axial inductors
L1, L2, L3, L4, L6, L7, L8.
These components look just like fat resistors, but they have a blue or green colored bodies. Inside the
device is a small coil wound on ferrite material. As before, refer to the parts list to select the correct one
for each position. L1, L2, L3, L4, L6 and L7 are mounted vertically. L8 is the only inductor horizontally
placed, and we recommend to separate it from the board approximately 1-1.5 mm (1/16 in).
Fit them on their designated places as with resistors.
Note: L5 is the VXO toroidal coil, which will be wound and placed later.
