“A classic keyboard from the 80’s. I bought this about 20 years ago, and it was pretty much in the same condition then as it is today. A bit of the brown paint has worn from the casing, and there are a few scrapes. All issues are shown in the photos. The side panel on the right hand side is broken at the back, as can also be seen in the photos, and a couple of the higher white notes are slightly damaged. These is the only real bit of physical damage on the unit. I have seen replacements for these for sale on eBay. The lowest white note on the left hand side (C) does not work. It presses down fine, but doesn’t trigger any sound and doesn’t send any midi data either. All the other keys are fully working, as are the screen, the number display and all the buttons on the front. The MIDI in and MIDI out are both fully functional, as are the mono OUTPUT socket on the back and the stereo (mono L/R) PHONES socket on the front. I don’t know about the other sockets on the machine as I don’t have gear I can plug into them to test them, but I don’t see any reason why they shouldn’t be OK too.

When i fired this up for the first time in a while recently, a low battery message was displayed on screen briefly. It has not reappeared since, so I think it was just because it had been off for so long (more than 5 years). I would rather leave it as it is, and leave the winning bidder to replace it if they want as I don’t want to break anything by opening it up. Also, I know that sysex and MIDI generally can be a bit of a daunting pain, so I have reloaded the factory presets and sounds. These will stay in memory just as long as that battery has life.” Click here to visit listing on eBay

“This Yamaha is in great condition. It does work well. There is some damage to the plastic button covering in two spots. This does not affect the functionality. It also has some other scuffs and scrapes in various places, but nothing too serious. The power cable is solid with no cuts or breaks. It comes with a soft carry case that is also in good pre-owned condition, as well as a music stand that slides into the back. Please see photos for a better understanding of condition. This unit does not come with a cartridge. ” Click here to visit listing on eBay

“Thanks for looking! Up for auction here is a well used Yamaha DX7. This unit plays and sounds great, and looks like it has seen decades of gigs. It has numerous scrapes and other cosmetic damage. One of the plastic corners is cracked, but has been repaired internally with layered epoxy and fiberglass. The photos show anything significant in the way of exterior flaws. If you value an actual relic finish, this one has it! 😁

You’ll also notice several Yellow Magic Orchestra (YMO) decals. I’ve attempted to contact the band’s management to see if they might have owned it at some point. Still waiting for a response. Obviously, they could have just been placed there by a fan who bought a DX7.

PLEASE NOTE: I make no claims that this instrument ever belonged to the band.

When the keyboard arrived at my repair shop, it had the same problem as they all do. It needed a new RAM battery and to have its voices reloaded. That’s it. I installed a new battery and socket for easy future replacements. A RAM cartridge containing the original Master group voices is included, just in case you ever need to reload them.

This unit is very clean inside. All I did was blow it out with compressed air. Please look at the photos of the innards.

This DX7 will serve you well, probably for decades to come.

When you purchase a DX7, you are buying a piece of history, so you become a part of the instrument’s story.” Click here to visit listing on eBay
