The polarized components are placed correctly: diodes and electrolytic caps.Visual inspection of the PCB bottom, there is no short circuits or long uncut leads.Double-check your PCB with the model, component by component, before powering it up.

Be patient soldering the big components perpendicularly, because they tend to be slightly tilted.

The positive hole is always square-shaped and it is marked with a "+" symbol.

Be careful with the electrolytic caps polarity, the negative lead (the short one) has to be placed in the round hole.

Pay attention to diodes polarity, there's a line indicating the correct position.

Soldering the components to the PCB is easy just follow the Bill of Materials and solder the parts, beginning with the small ones.

You will need a soldering iron, lead, and cutting pliers. Here's a summarized version from our full documentation.

Designed as a small and portable 1 watt amplifier loaded with all the features of big amps, the project was fully developed using only open source tools-like KiCAD, a design suite to create schematics and layouts in any platform. Welcome to the communityĮlectroSmash just released an open hardware guitar amplifier called the 1Wamp.
