The boards are designed the way that the legs of the diodes and resistors should be
bent close to the body downwards before inserting them:
Start soldering the three diodes, following the direction (black mark x up, 2x
left).
Solder in the resistors. The values can be determined from the colour codes or
measured with a meter:
3x 220ohm = red red black black brown
x k = brown black black brown brown
2x 2k7 = red violet black brown brown
2x 0k = brown black red brown
x Meg = brown black black yellow brown
IC socket with the marking to the left
Red and green LED - note the direction: short leg (-) into the square soldering
eye.
Solder transistor 2N3904 slightly to the left above the IC socket and voltage
regulator 78L05 further to the right. Note the given direction.
00nF film capacitors ( 04), 0uF electrolyte (note the direction here: white
marking = minus), 00nF ceramic capacitor ( 04)
Solder in 2x uF film capacitors ( 05)
2x mini push-button
3.5mm SMD jack sockets: ( ) apply solder to one pad, (2) solder the corresponding
leg, (3) align the socket again, (4) solder the remaining pads.
3x Mini Switch: It is best to solder leg first, align it again, then solder the
rest.
Solder the 3 potentiometers using the same technique.
Attach the 6.35mm sockets from below and solder them on the top.
Attach the DC socket from below (again with a pad first).
Shorten the wires from the battery clip to about 4cm, then strip them and wet the
bare wire with solder.
Apply some solder to the plus and minus pads. Now solder the pre-tinned wire ends
to (+) = red and (-) = black.
Done!
It's best to check all solder joints again for unwanted bridges or bad solder
joints before testing for the first time...
Have fun with the synth!
