MP 5.12 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 :
• MP512 Schematics
• MP512 Components layout
• MP512 Parts list
• MP512 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.
MP 5.12 Assembly guide
1.

DOA Pin Sockets

Solder the 7 pin sockets for the DOA. Solder one at a time. Insert one
socket, turn over the PCB and press against a solid but flexible surface like
cork or dense foam then solder. The correct positioning of the sockets is
very important for easy insertion of the DOA.
2.
Add D1 to D4, D6 to D11. 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.
3.
Add R1 to R40. The resistors marked NC in the parts-list should not be installed.
Control the resistor values with a digital multimeter. Bend the leads at 0.4" with a lead forming tool.
4.

Integrated Circuit

Insert U2 and solder. You will need to bend the pins slightly inwards before inserting. Make sure you are
not charged with electrostatic electricity before handling the IC (or remove your shoes).
Warning
: Make sure to respect the IC direction, marked by a notch. Do not use a socket because it
would be to high for the Di01 board.
5.

Inductor

Add L1. Bend at 0.8".

Visual check At this point, brush the solder side with a hard tooth brush to remove any remaining solder bits. Make a full visual check. Any missing component on the board ? Any remaining component in the box ? When everything looks correct, proceed with the frame assembly.
