  • Page 5 3. The distance between pcb and frontpanel is just 10 mm. We have to ensure the parts are placed as flat as possible on the pcb. The wires of the resistors should be bent directly near their bod Building instructions 'Eurorack Spring Reverb' V1.0 - 06.2014 © Stereoping Germany, Hattingen 2014...

  • Page 7: Let's Get Started

    This is the relevant pcb-orientation when we talk about something like "diode in the upper right corner of the pcb". Building instructions 'Eurorack Spring Reverb' V1.0 - 06.2014 © Stereoping Germany, Hattingen 2014...
  • Page 8 The Spring Reverb has 3 IC-sockets - two with 8 legs and one with 14 legs. They have a small notch on one of it's shorter sides. The notch tells you where to put the side of the IC with pin 1, which is quite important.
  • Page 9 IMPORTANT! The pinhead is soldered on the backside of the pcb which is the side without silkscreen where we normaly solder the parts. Put the pinhead with it's short legs ahead onto the pcb and solder it from the silkscreened side. Building instructions 'Eurorack Spring Reverb' V1.0 - 06.2014 © Stereoping Germany, Hattingen 2014...
  • Page 10 Now solder the jacks and remove the frontpanel to continue adding the rest of the parts. Building instructions 'Eurorack Spring Reverb' V1.0 - 06.2014 © Stereoping Germany, Hattingen 2014...
  • Page 11 You can solder it now or add some other resistors first. After soldering, use the side cutter to cut the wires directly above the solder. Building instructions 'Eurorack Spring Reverb' V1.0 - 06.2014 © Stereoping Germany, Hattingen 2014...

  • Page 13 So you can add them now. Please remember, they want their longer leg in the drilling hole marked with a "+". The big 33µ-Elko will be soldered at least. This is the way, your pcb should look afterwards: Building instructions 'Eurorack Spring Reverb' V1.0 - 06.2014 © Stereoping Germany, Hattingen 2014...
  • Page 14 Now solder the jack with a lot of solder. The jacks must withstand some mechanical forces later. Building instructions 'Eurorack Spring Reverb' V1.0 - 06.2014 © Stereoping Germany, Hattingen 2014...
  • Page 15 If you prefer, you perfectly can bend it FIRST and solder AFTERWARDS. Keep an eye on the right polarisation, the golden stripe is the minus-end and should point towards the eq-pots. Building instructions 'Eurorack Spring Reverb' V1.0 - 06.2014 © Stereoping Germany, Hattingen 2014...
  • Page 16 We definately MUST ensure, the pots are sitting in position on both of it's sides before we solder them. What can happen in Building instructions 'Eurorack Spring Reverb' V1.0 - 06.2014 © Stereoping Germany, Hattingen 2014...
  • Page 17 The pics above show you how to do it (green) and what mistakes you should have a look for (red). Building instructions 'Eurorack Spring Reverb' V1.0 - 06.2014 © Stereoping Germany, Hattingen 2014...
  • Page 18 All parts should have found their places on the pcb now and in front of you there are just 3 ICs remaining (apart from the redundant resistor R4). Time to get the module into operation. Building instructions 'Eurorack Spring Reverb' V1.0 - 06.2014 © Stereoping Germany, Hattingen 2014...
  • Page 19 Attach the power-cable like on other eurorack modules with the red wire pointing to the bottom of the module. Building instructions 'Eurorack Spring Reverb' V1.0 - 06.2014 © Stereoping Germany, Hattingen 2014...
  • Page 20 Switch on the power supply. Grab your multimeter and check the voltages like in the following photo. You can get Ground on any of the pots metal clamps. Building instructions 'Eurorack Spring Reverb' V1.0 - 06.2014 © Stereoping Germany, Hattingen 2014...
  • Page 21 Then you just press it down until the thin part of it's legs disappear in the socket. After having installed the remaining ICs we start to check functionality. Building instructions 'Eurorack Spring Reverb' V1.0 - 06.2014 © Stereoping Germany, Hattingen 2014...
  • Page 22 Connecting to the reverb tank We connect the Spring Reverb module with the reverb tank using an ordinary cinch-to- cinch-stereo audio cable as shown in the pic. This solution has a lot of benefits: such cables can be bought anywhere quite cheap and in different lengths.
  • Page 23 The other red jack on the other end of the cable connects to the reverb tanks "Input"-jack. The black side of the cable connects the tanks "Output" with the "Return"-jack of your module.

  • Page 24 Now turn Mix back to have more dry than wet ratio and slowly increase the • Send Level. The tank should increasingly distort. By playing with current Limit and the EQ you will find out everything about your tank's sonic potenial.

  • Page 25 Congratulations. You made it, you assembled your Spring Reverb and everything works as it should! Now take your time to attach the frontplate and screw the nuts on the jacks with a long nose plier or other some suitable tool. Be careful not to scratch your cute frontpanel.
