Roland S-760 Rotary Encoder Replacement DIY
There are two ways to replace an S‑760 rotary encoder:
The Quick & Easy MethodWith a suggestion by Ray Bellis, I've designed a replacement encoder PCB. This new PCB uses the existing connector and wiring harness on the sampler. Simply solder the old encoder board wires and a new low‑cost replacement encoder onto this PCB and pop it in place. There's no cost markup or profit and OSHPark will ship it free to you if you are in the USA, Brazil, Europe, United Kingdom, Russia and beyond (Note: OSHPark sells a minimum of three PCB's at a time. The price works out to about $1 per PCB. A super bargain... especially if you own more than one S‑760 !!!)

The MacGyver MethodThese are instructions from the old method I used before creating the new PCB. It requires some un‑soldering/re‑soldering, extra wires and re‑using the existing encoder PCB and wiring connector harness. It's a lot of extra work but the price is minimal... Under $3 (USD).

Safety Precautions and Disclaimer
Modifications made to any factory stock equipment will always pose an element of risk. Sometimes mistakes are made which are irreversible. Improper soldering and handling of electricity can cause serious injury and damage the synthesizer. Use caution when handling static sensitive devices and the PCB. Make sure you are properly grounded, working on a static-free workbench or table and wearing eye protection during any soldering tasks. The author is not responsible for any damage or injury resulting from this DIY info. Use this DIY information at your own risk. And, I can't stress enough, the importance of wearing eye protection while soldering. That stuff flies everywhere sometimes!
