TABØR
build guide v1.1
∞
Hi fellow!
Just a quick intro before starting,
TABØR is made of two boards:
•brain board with all the electrolytic capacitors, vactrol, ICs and reverse polarity protection
components
•control board with all the potentiometers, jacks, LEDs and the 2 legs avalanche transistors
Following this guide, the boards are assembled by the height criteria: short components first, tall
components last.
At the end the two boards are connected thanks to their headers and the panel mounted.
Be careful to check the correct position of the two boards while connecting them and before
powering up the module: potentiometers legs must face down on the control board and power
socket must be up in the brain board.
Another tool that can help you finding the components on the boards are the interactive BOMs

Download them and open the .html file with a browser. You can use them to check where a
component is located on the board. They work also offline.
now let’s begin!
brain board
ceramic caps:
Snap them in. Don’t mind their polarity.
tip: since they are of the same height, you can wait and solder all the ceramic caps, diodes and
resistors at the same time after you’ve placed all of them on this side of the board.

diodes:
They are placed in vertical position: mind their polarity, the circular line (white) on the PCB needs to
match the circular line (black) on the component.

resistors:
They are placed in vertical position.
The body of the resistor goes on top of the white circle marked on the PCB.
tip: they don’t have a polarity; this precaution is due to avoid them touching while soldered.

transistors:
The “D” shape white symbol on the PCB needs to be aligned with the “D” shape of the transistor that
needs to be soldered.

ICs:
Place the sockets matching the drawings on the PCB, be careful of the notch direction.
tip: flip the board, bend one of the socket legs and solder that leg. Check if the socket is
aligned with the PCB. If so solder all the other pins.
Place the ICs and be careful of the notch direction.

headers:
Short legs are what needs to be soldered: Insert the short legs inside the hole.
Always check if you are on the right side of the board by looking at the drawings and texts on the
PCB: the header’s body needs to match the drawing on the PCB.
tip: solder one pin and check if the header row is aligned and perfectly vertical with the PCB.
If so solder all the other pins.

you deserve a good cup of coffee now
done?
ok, flip the board

diodes:
They are placed in vertical position.
Mind their polarity, the horizontal line (white) on the PCB needs to match the horizontal line (white)
on the component.

eurorack power socket:
Place the socket matching the drawing on the PCB.
tip: solder one pin and check. If the socked is aligned solder all the other pins.

vactrols:
Match the short leg of the vactrol with the squared solder pad on the PCB.
tip: it’s easier to bend at 90° degree all the four legs before trying to fit the vactrol in place.

resistors:
They are placed in vertical position.
The body of the resistor goes on top of the white circle marked on the PCB.

transistors:
Remove the middle leg of the transistors (pin 2: the base).
tip: you can gently move it back and forth until it breaks, or you can cut it - the shortest possible
- with a wire cutter.
the “D” shape white symbol on the PCB needs to be aligned with the “D” shape of the transistor.

LEDs:
Short leg goes into the square pin (bottom).
Remember that Y stays for yellow LEDs, R for red, G for green and B for blue
tip: the closer to the PCB, the more they will be diffused on the panel’s hollow window.

At last put the panel on - check its direction - tighten the nuts and then solder all the surface
components.
tip: we are soldering them now to ensure that all the surface components are aligned with the
panel
Put the knobs on the potentiometers and tight their screws where necessary.
check if everything is in place and then you are done with the control board
Make a sandwich with the two boards considering their direction and connect the power supply

tip: mind the polarity on the header socket on your case, remember that red line is -12v
