MP 599 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.

MP599 Test 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 connection between the top and bottom pads is already 
done. 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.
Cut the component leads and pins totally flush with the PCB after soldering. A too long tail could create 
an electric connection with the side plate.
Here are two excellent introduction to soldering videos:

MP 599 Main board Assembly guide

1. PCB split

Split the PCB into 3 parts along the 
grooves (red lines on the picture). 
Use extra thin sandpaper to polish 
all the rough sides.

2. DOA Pin Sockets

Solder the 7 pin sockets for the DOA. Solder one at a time.
Depending on the tin thickness on the PCB you may have to press 
quite hard to fit them into their hole.
The correct positioning of the sockets is important for easy 
insertion of the DOA.
