MP573 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 :
•
MP573 Schematics
•
MP573 Components layout
•
MP573 Parts list
•
MP573 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.
Soldering
All the PCB holes are metallized. It means the connections between the top and bottom pads are already
made. The parts must be soldered only from below (unless differently stated).
Use only small diameter solder, 0.5 or 0.7 mm, 1mm maximum. Use the minimum possible amount of
solder. Bad joints are almost always caused by too much solder.
Here are two excellent introduction to soldering videos:

MP573 Assembly guide – PCB split
1. PCB split
Split the multiple PCB along the
red lines on the picture.
This will separate the main PCB,
DI PCB, input & output
transformer PCB, link PCB's and
the protection cover.
Clean up the break line with very
thin sand paper.
There are two additional safety PCB's available: One input transformer PCB and one output transformer
connector PCB. These won't be used for this build.
