Switcher-2 Assembly guide
Safety warning
The kits are main powered and use potentially lethal voltages. Under no circumstance should someone undertake the
realisation of a kit unless he has full knowledge about safely handling main powered devices.
Please read the “DIY guide” before beginning.
Print or open the following documents :
• Switcher-2 Schematics
• Switcher-2 Components layout
• Switcher-2 Parts list
Follow this guide from item number 1 till the end, in this order. The assembly order is based on components height, from
low to high profile, in order to ease the soldering process : The component you are soldering is always taller than the
previously assembled ones and it is pressing nicely against the work area foam.
Switcher-2 Assembly guide – Main PCB
1. Ceramic capacitors
Add C4, C5, C7, C8.
C3 which is placed
under the PCB will be installed later.
2. Resistors
Add R1 to R5 and R8. R7 will be installed later in order to leave an easy access for soldering the
transformer.
The resistors are installed vertically.
Warning
: It is very important to check the resistors value with a DMM because the colour code can be
ambiguous. For example 1K (brown-black-black-brown-brown) can be confused with 110R (brown-brewn-
black-black-brown).
