Building Tips
1- Pay attention to the orientation of the 3PDT ! In the following picture
you can see how the 3PDT pins should be positioned (inserting the pins
in the holes can be a bit tight to avoid movement while soldering):
2- For a proper soldering you just have to apply the right amount of solder
wire . A right solder joint should have a concave shape around the joint
and look like this:
3- Don’t apply too much heat! When soldering, the time you hold the
solder iron against the joint should be as short as posible to avoid
damaging any part (a few seconds should be enough). If you can’t get a
solder joint right,
let it cool
a bit before trying again.
4- If having troubles with the building, checking the schematic in the last
page will help you find where the audio signal stops . When you find the
spot, check out that everything around that joint is ok (components
placed at their right place, solder joints…).
