KASTLE v1.5.2 - Assembly Guide
(also applicable for KASTLE DRUM)
INTRODUCTION
Welcome to the assembly guide for the Kastle (or Kastle Drum) DIY kit - mini modular synthesizer. It
is suitable for beginners. 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 some of

or
everything faster and better.
The Kastle kit consists of just one PCB. All the parts come in two bags separated for the soldering
and assembly parts. Please check all of your parts BEFORE you begin work to make sure you are not
missing anything. See the bill of materials for detailed list.

SOLDERING RESISTORS Start the soldering with the resistors. There are just three values of them: 1k (11x), 100k (7x) and 220k (2x). Before you start soldering, check the values by using a multimeter or you can check the color codes - the 100k's have the orange stripe. Then snip the leads close to the PCB (be sure to make this step on all remaining leads in the course of this guide) and set aside a few of them. - Page 5 JACK CONNECTORS Add the 3,5mm jack connectors (2x). IC SOCKETS Insert the IC sockets (2x; 8 pin DIL). Just be aware of the right direction of sockets - there is a notch on the sockets that has to match with the notch sign on the PCB.

CERAMIC CAPACITORS Add the ceramic capacitors now. There are just five of them of the same value - 470nF (they are marked "474" on itself). FEMALE PINHEADERS Now let's do the female pinheaders: 2 pin ones (6x) and 3 pin ones (8x). It may take a little patience to insert them well. - Page 7 WIRES You will need the cutted leads from resistors now. Put these wires through the "HOLD”, "BAT_-” and "BAT_+” holes and solder them. The leads can’t be connected with the potentiometers on the other side. CLEANING (OPTIONAL)

Page 8: Last Check
Before you begin to move forward, 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 (don’t let it flow into the pots), let it act for a while and sweep it off . - Page 9 Mount the holder with spacer and the longer screw. It may be a little tricky. Don’t tighten the screw too much because you are dealing with plastic material, you know. And now the last soldering challenge! You have to connect the leads with the lugs. Do not let the lug heat too much! (it would break the connection of the coil and the lug, use just the tip of your soldering iron).
- Page 10 (Note: at this point you can make a pretest before putting enclosure on by turning the unit on.) YOU ARE ALMOST DONE... Unmount the washer and nuts from the switch. Keep them aside. complete the Kastle with the plastic case parts. Start with the side parts (push them just in the corners).
