Welcome to the Toob Screamer Assembly Instructions. Except for the battery clip this kit does not use any wiring and everything is attached directly to the PCB, making it easy to make a very nice looking build. Lets get started!

BOM Layout

If you’ve received your kit and are ready to build, the first step is to ensure you have all of the parts and familiarize yourself with the PCB and where the parts will be going.

Check your kit against the Toob Screamer BOM. If you are missing anything let us know and we will ship you the part.

Assembly

Resistors

There are 18 resistors and 4 diodes to install. The resistors are not very sensitive components and are not polar components, but the diodes are polar components and must be soldered in the correct direction. On the silkscreen of the PCB for each diode there is a line on one end. You will want to match the line on the diode with the line on the silkscreen of the diode.

Capacitors

Here you will want to pay especially close attention to two of the ceramic capacitors because two of them are polar components while the rest are not. All of the electrolytic capacitors (C9, C10, and C11) are polar components. The longer lead on the electrolytic capacitors go into the hole that is marked with a ‘+’ sign. And then the two tantalum capacitors (C5, C6) that look like the other ceramic capacitors are also polar components and, like the electrolytic capacitors, you need to ensure that the longer lead gets inserted into the hole marked with the ‘+’. All of the other capacitors are not polar components and you can insert them in any direction.

LED, Transistors, and IC Socket

Next we will install the LED and Transistors. Both of these components have one side that is flat which match up to the silkscreen on the PCB board. If you have a hard time identifying the flat side on the LED, the side which has the shorter lead has the flat side. And then the IC socket will have a notch on it that you will want to make sure aligns with the notch on the PCB’s silkscreen.

Power Adapters, Switches, and Pots

Next you will want to install the Pots (R19, R20, R21). When soldering the pots into place you will want to also solder in the side-clips to ensure that the pots are secured to the PCB and will not easily come loose. For the battery clip, ensure that you attach the red wire to the ‘+’ point and the black wire to the ‘-‘ point. And then solder the switches and the DC power jack into place.

When installing the pot, some pots come with nubs near the shaft that may get in the way of installing the circuit into a case. Check for a nub and clip as necessary.

Stomp Switch and Audio Jacks

We’re almost done! The audio jacks will be easy to install, just make sure you install the mono jack into side that only has the two holes and not into the mounts for the stereo jack, which will have a total of six holes. And then when you install the stop switch, make sure that the sides of the switch that are all the blue plastic are facing the top/bottom of the PCB while the sides of the stomp switch which have the metal draped over are facing the sides of the PCB. If you can’t get the stomp switch to go in, don’t force it, try it in a different direction.

Project Completed

Congrats! Your Toob Screamer is complete. Hook it up and have some fun!
