You're watching the ribbon that connects the Dynascan board of Roland D-50 (both versions) to the keyboard. This is a source of problems, specially if your synth was frequently maintained or or had problems with water!! I can also provide you the ribbon connectors and all the parts needed to repair key problems - and D-50 has some.

Check my other items - decent prices for top products sent immediately, well packed and tracked mail.

These are NEW products, not new old stock. I have sliding pots for most vintage gear, including most Korg, Yamaha and Kurzweil. Some rotary for older Moog (Micromoog) and Transcendent 2000. Also some switches and some SSM and Curtis (CEM) chips. I will be selling all these in the next few weeks. Contact if you are looking for something. I repair (and collect) synthesizers since 1992.

I will send worldwide (tracked) for free. I'll ship same day or next, depending on payment hour.
