Solder the diodes ( D1, D2, D3, D4) watching polarity. Black line on the diode must be in the same place as white line on the diode PCB silkscreen.
Solder the two ferrite beads (FERRITE+, FERRITE-) passing trough a recycled resistor leg
Place the sockets (IC1, IC2, IC3, IC4, IC5) and solder them. Then place the ICs on them taking care of polarity. To do that the mark on front must match the mark on the socket.
IC1=555, IC2=4013, IC3=4052, IC4=TL074, IC5=TL072.
Solder the transistors 2n3906 (T5, T6) and 2n3904 (T1, T2, T4, T7, T3). Be sure they are on proper position (same as the silkscreen on the PCB)
Solder the power connector been sure the position is correct (as in the silkscreen)
Solder the male pin header (Circuit) by the short part and by the silkscreen side of the
PCB. Ensure they are at 90º from the PCB.
PCB2: (the big one)
Solder the resistors. Using a multimeter to doublecheck values is recommended.

Place and solder the Female Pin Header (Panel To) by the opposite side of the faders, ensuring it is 90º from PCB.
Solder the toggle switch
Solder the faders (A, D, R, S), ensuring they are totally strait. If is not possible because they touch the back side of the pin header (Panel To) cut a little bit the header pins.
Put LED on place (LED01) respecting the polarity but don't solder it until you screw the front panel. This way is much more easy to solder it on the right position.
Solder the minijack or the Banana (ATTACK, DECCAY, GATE_IN, OUT, RELEASE, SUSTAIN,
TRIGG_IN).
Put the spacer on the tree holes by the male side and fix the with the tree nuts
Put the push button on place but don't solder it yet.(Because the same reason as LEDs)
Place the front panel, screw the minijacks or bananas and the push button and poceed to solder them
Solder the LED on the right height
Assembly the PCB 1 on the PCB2 and screw them with the tree provided screws
Endless sustain Fix.
In order to improve sustain behavior, we will do a fix to control board (smallest one)
We will solder a 2N3906 transistor and a 1n4148 diode, both provided in a separate bag. See picture for reference.
Best way will be to solder the diode to the base of the transistor (center leg),bend it, and solder the other two legs in marked points, making sure labeling is facing you. Then solder the other end of the diode.
No need to say that making sure they do not touch other solder points is quite adviceable!
