M 566 Assembly guide
Safety warning
This kit use high voltages that are potentially lethal. Under no circumstance should someone undertake the realisation of
this kit unless he has full knowledge about safely handling high voltage powered devices.
lease read the “DIY guide” before beginning.
rint or open the following documents :
•M 566 Schematics
•M 566 Components layout
•M 566 arts list
•M 566 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 CB 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.
Warning : Some components on this board carry high voltages. It is compulsory to cut the component
leads and pins totally flush with the CB after soldering. A too long tail could create an electric arc with
the side plate.
Here are two excellent introduction to soldering videos:

M 566 Assembly guide – CB split
1. CB split
Split the multiple CB along the red line on the
picture.
This will separate the tube CB, the DI jack CB,
the power-up CB and the protection cover.
Clean up the break line with very thin sand paper.

M 566 Assembly guide – Main CB, B side
2. B side
The M 566 main CB carries components on both sides. The A side is the side with the title writing
“M 566”. We will start by the B side which holds only a few components.
3. Diodes
Add D5 to D9. 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 CB marking.
4. Resistors
Add R24, R25, R36 to R44.
Control the resistor values with a digital multimeter. Bend the leads at 0.4” with a lead forming tool.
5. Integrated Circuit
Insert U3 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 under the CB.
6. Ceramic capacitors
Add C19 & C20.
7. Transistors
Add Q1. It must be placed flat on the CB, flat side against CB.
Warning : Watch out the transistor direction.
8. Led
Bend the leads of D10 right angle at 6mm from the body taking care of the
anode position (the longest lead).Insert from the CB B side and solder with
the leads at 2mm from the CB surface.
Warning : it is easy to bend the
leads in the wrong direction !

9. A side
Turn the board over, A side up. Make sure all the B side component leads have been cut as short as
possible.
10. Diodes
Add D1 to D4, D11 to D14. Use a lead forming tool to bend the leads at 0.4”, except for D14 which
is bent at 0.6”.
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 CB marking.
11. Resistors
Add R1 to R11, R13 to R18, R20 to R23, R26 to R35, R45, R46, R51. The resistors marked NC
(like R33) 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
except R34 which is bent at 0.6”.
12. IC Socket
Insert and solder the socket of UI. Do not insert U1 at this time.
Warning : Make sure to respect the socket direction, identified by a notch on the socket and a dot on
the CB.
13. Test pins
Solder the 8 test pins T 1 to T 4, 0V, V+, V- and T 8.
These pins are inserted from the top CB side, long tail up. They may require some pressure for
insertion. After soldering, cut flush on the solder side.

28. otentiometers 1 & 2
lace the bracket on the potentiometer bushing, and attach it with the lock washer and nut. Tighten.
Insert potentiometer and bracket into the CB holes. Solder the central potentiometer pin. Now check
that the potentiometer shaft is perfectly parallel to the board.
Warning : Do not only rely on the bracket being flat on the CB, it sometimes need little visually made
adjustments to get a perfect position.
Once the position is correct, solder the other pins.
Finish tightening the nut, without excess.

35. Frame assembly
Attach the side panel to the front plate with two M3x6 black
countersunk screws.
Warning : Do not confuse the M3x6mm countersunk black screws
with the #4-40 3/8" black screw that are used to attach the
module in the lunchbox.
36. DI CB (B)
Solder the jack socket to the DI jack CB, on the side marked CN1, the
jack opening on opposite side of the connecting 6 pads row.
Cut the pins short.

37. DI jack CB assembly
Insert the DI jack CB into the 6 pins header located in the lower left corner of the main CB. Do not
solder yet.
lace a flat plastic washer on the jack socket and put the main CB in place on the frame, switches and
pots going through the front panel. Watch out the LED position.
Screw in the jack nose with the bevelled plastic spacer inserted.
Attach the CB to the frame with three 25mm spacers, leaving out the fourth spacer near the jack.
Solder the 6 pins of CN1on the DI Jack CB.
Remove the 3 spacers, the jack nose and remove the CB from the frame.
38. Input transformer
It is necessary to leave a small gap between the transformer and the CB surface in order to avoid any
electrical contact between the metal case and pads. Fit two layers of double sided adhesive tape, under
the transformer, between the pins. It is not necessary to remove the second protective layer from the
tape as it is only used as a spacer.
Insert the transformer. Start soldering 2 opposite pins, check the position, adjust if necessary then
solder the other pins.
39. Large electrolytics
Add C22 and C23.
Solder one lead first, adjust verticality then solder the second lead.
Warning : The +lead must go into the +hole. Do not reverse (they may explode !)
40. U1 & U4
Insert U1 & U4 into their respective socket. 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.
41. 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 test.
42. Functional test
We are going to do a first test before soldering the output transformer. Because the clip LED circuit is
placed below the transformer, correcting a possible mistake would be easier without it.
lease follow the testing guide M 566-test-guide.pdf.

pots going through the front panel. Watch out the LED position.
Screw in the jack nose with the bevelled plastic spacer inserted.
Attach the CB to the frame with four 25mm spacers, with four lock washers inserted.
