TIMBER v1.1 - Assembly Guide
bastl-instruments.com
INTRODUCTION
This guide is for building TIMBER module from Bastl Instruments. It is good to have basic soldering
skills and to be able to identify electronic components before starting this kit. However if you have
never soldered before, check out this tutorial first .

The TIMBER kit consists of two boards. All the parts comes in three bags separated for Top board,
Bottom board and Assembly parts. See the Bill of Materials (BOM) for detailed list. We even included
some of the best quality solder to help you solder everything faster and better.

BEFORE STARTING THE KIT...
Before starting this kit, prepare the following tools:
●
Soldering iron
●
Multi-meter
●
Flush cutters
●
Smaller pliers
●
n2. hex screwdriver or allen key (enclosed with kit)
●
Phillips screwdriver
●
Wrench No. 8
●
Protective eyewear
●
Isopropyl alcohol + smaller and clean brush (optional)
We suggest that you work in a clean and a well lit and ventilated environment to avoid accidents or
losing any of the small components. Also briefly go through this guide and make sure that you
understand all the steps before you start soldering.
4
Start with the bottom board parts. First of all, take your time and check the values of all resistors
using a multimeter (or you can check the color codes if you are seasoned enough):
2
-
470R (4x), 1k (3x), 4k7 (1x), 22k (1x), 68k (1x), 100k (30x), 150k (1x), 270k (1x), 330k (2x),
680k (1x), 2M2 (1x).
Then solder them on the bottom PCB and snip the leads close to the PCB (be sure to make this step
on all remaining leads in the course of this guide).

5
Solder also the diodes. There are actually five types of them: 1N4007 (2x), 1N4148 (2x), 1V zener
diode (4x), 2V4 zener diode (3x) and 4V7 zener diode. Be careful, diodes are polarized!
Make sure that the marking ring on the diode body matches the marking on the circuit board. Check
the photo below.
9
Now solder the IC sockets (3x 14 pin and 1x 16 pin). Make sure that the notch on the socket
matches the print on the board.
MALE HEADERS
Move to the male pinheaders now (one 2 pins and one double 5 pins right angled). First help
yourself with connecting the power cable to the double pinheader (see the picture). Then place it on
the board and solder it. The other 2 pin male is a piece of cake. Just place it on the board facing it by
longer part to your face and solder from the other side as with the previous pinheader.
11
Let’s do the ceramic capacitors. These parts are not oriented. There are six values of them:
-
47pF (2x, marked “470” on itself)
-
560pF (4x, marked “561”)
-
1nF (1x, marked “102”)
-
10nF (1x, marked “103”)
-
100nF (8x, marked “104”)
-
470nF (2x, marked “474”)
12
Let’s do the electrolytic caps (2x 10μF). These ones are polarized! There is a plus (+) sign on the
PCB that has to match the longer lead of the electrolytic capacitor (actually the minus (–) side is also
marked on the body of the capacitor with a white strip).
FUSES
Solder the two fuses right on the rectangular spot signed “PTC”. These parts look quite similar to
capacitors so don’t let it confuse you.
15
Next don’t forget to place ICs into the sockets (1x V2164, 3x TL074P). There is a notch on each IC
that should match with the notch on the socket (this is super IMPORTANT!). Installing ICs can
be also a little tricky. You should bend the IC leads in slightly with your fingers. Then press all the
leads into the sockets in one shot.
BEFORE THE LAST STEP FOR THE BOTTOM BOARD… (FEMALE HEADERS)
As you can see one female pinheader left. Hold on with this part. You will use it in later steps.
For now you are finally done with the bottom board. Make the last check that all parts are on the right
place and everything is properly soldered.
16
Let's move to the top PCB now. Again, start with the resistors:
-
1k (4x), 10k (2x), 22k (2x), 43k (2x), 68k (1x), 82k (2x), 100k (12x), 150k (1x), 1M (1x)
17
Next solder the 1N4148 diodes (6x). Be careful again, diodes are polarized!
20
Add the tiny male pinheaders from the other side of the board (one 2 pins and one 3 pins). Just be
careful to solder them straight.
IC SOCKETS
Move to the IC sockets (1x 8 pin and 1x 14 pin). Watch out for the orientation!
21
Now add the ceramic capacitors. There are just seven of them in three different values:
-
47pF (1x, marked “470” on itself)
-
100nF (4x, marked “104”)
-
470nF (2x, marked “474”)
22
Now it’s time to connect the boards with pinheaders.
1)
Mount the spacer with the screw to the bottom board first.
2)
Insert male header into the female one.
3)
Put the header on the bottom board facing the female one down.
4)
Place the top board on and secure it with the other spacer. Check the position and do the
soldering of headers finally.
23
Before the last soldering run, insert the ICs into the sockets (1x TL072, 1x TL074P). Again, watch out
for the notch orientation! (for TL072 is relevant the dot on it)
24
JACK CONNECTORS, POTENTIOMETERS & SWITCHES
You are almost done. Let's do the rest of the components by just putting them in first (no soldering
yet! - It starts at point 7!):
1)
Unmount the top board.
2)
Mount the spacer to the front panel.
3)
Check the set of potentiometers now. There are five of them of four kinds (see the picture
below).
a)
First, check the center detent ones (2x) and place them at their spot on the board
(the longer one goes to the bottom line).
b)
The other taller one goes also to the bottom line on the right. The last two ones goes
to the spots that left. Be sure that the pots are placed in the right angle and they are
right on the board.
25
Check the switches: three-position ones (3x) goes to the top line, the two-position one is
placed in the bottom. The orientation doesn’t matter on these parts.
5)
Insert jack connectors (9x).
27
Place the front panel on the top board and mount the jacks.
7)
Mount the spacer with the other one. Check the position of all the parts if they are flat on the
board and at the right angle and do the soldering (SOLDERING TIP: you can start by
soldering just one of the leg at each component so you can make adjustments easier by
reheating)
CLEANING (OPTIONAL)
After the soldering is done you might want to clean your PCB. You can use e.g. isopropyl alcohol. Put
some of the liquid all over the PCB using the brush (be aware to not let it flow into the pots), let it act
for a while and sweep it off. Then just let it dry. You can repeat these steps until you are satisfied with
the result.
28
Congratulations! You have made it through, your TIMBER is ready to work! Just add the knobs and
set the jumpers as you want (see the photo and manual). Before you connect anything, make sure
that your system is disconnected from power. Also double check the polarity of the ribbon cable, the
red cable should match the -12V rail both on the module and on the bus board!
TROUBLESHOOTING
