Introduction Thank you for purchasing an LED slider upgrade kit for your ARP synthesizer. These sliders not only look great, but they feel better than the original ARP CTS sliders. This installation guide will show you how to install the slider kit and the 5 volt power supply.
Tools Required For Installation • Phillips Head Screwdriver • Solder • Center Punch or Marker • Drill • Soldering Iron • Wire Strippers • Desoldering Tool (Such as Hakko 808 or Similar) Installation of Sliders 1) Remove all slider caps from the ARP, then remove all PCBs from chassis. Desolder all old CTS sliders and remove them from the boards.

2) Using the PCB parts diagrams in Drawing 1,2, and 3, place all of the slid- er assemblies into the PCB as shown in figure 1. DO NOT SOLDER YET. This allows for the chance to test fit the assemblies, and also makes it easier to wire the sliders together.

Figure 3 - Sliders Assembly Tack Soldered (Each slider soldered in place by only one pin) Now that the slider asseblies are held in place, heat up the tack solder joint holding each slider into place and adjust so that slider shafts are perpendicular to the pcb and the slider PCB is parallel with the ARP PCB.

INSTALLING LED POWER 1) The 5V LED ballast should be mounted close to the transformer in your ARP’s power supply. The ballast is powered by the AC hot and neutral, the same as the transformer on the ARP. Find a location near the transformer where the ballast can be mounted. Use the mounting template and make starter marks using a punch.

5) On the ARP, one side of the AC is switched on and off by the power switch. This wire also runs through a 250V 500mA fuse. Attach the ballast AC inputs at the same spot the primary winding of the transformer attach to the AC and the fused AC.
