DKC-850 Conversion Cables: What They Do and How to Buy

In my Disklavier Upgrades guide article, I make reference several times to DKC-850 conversion cables. These are the cables you use to connect your older Yamaha Disklavier to a newer DKC-850 control unit (or a DKC‑800 converted to act like a DKC‑850).

Disklavier DKC-800/850 Adapter (PJP-PS02 Replacement)

Unlike full E3 systems, the DKC-800 and DKC-850 piggybacked upgrades are powered by external AC adapters, such as the PJP-PS02.

Why Disklavier Floppy Drives Fail (And How to Back Up Disks)

Choosing the Best Surge Protector for your Disklavier or Keyboard

Electronic keyboard instruments—especially Yamaha Disklaviers, Clavinovas, stage pianos, and organs—represent significant financial investments. Some of these instruments cost well over $50,000.
