EQ573 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.

EQ573 Setup guide
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.
EQ573 Assembly guide – Main board
1. Diodes
Add D1 to D5. Use a lead forming tool to bend the leads at 0.4”.
Warning
: Make sure to respect the direction of the diodes which is marked by a ring on the component
and a double line on the PCB marking.
2. Resistors
Add R17 to R66.
Control the resistor values with a digital multimeter. Bend the leads at 0.4” with a lead forming tool.
3. Test pins
Solder the 5 test pins TP1 to TP5.
4. Ceramic capacitors
Add C79, C87.
5. Film capacitors
Add C24 to C49, C51, C53 to C55, C57 to C75, C80, C81, C84, C88, C89, C92.
