Yamaha DX7 Project Machine

“Up for auction is this nice Yamaha DX7 FM synth. It appears to be in good condition aside from the big crack in one of the plastic side panels. I plugged it in and turned it on and it makes sound. I only played it briefly through a practice amp so I can’t really comment on the quality of the sound but it sounded nice to me. The buttons certainly change the sound and you can switch between the internal presets and the cartridge that is included. The cart is #4 Orchestral & Percussive Group / Complex & Effects Group. ” Click here to visit listing on eBay

Yamaha DX9

“I bought this synthesizer originally from a music store in suburban Chicago so I am the only person that has owned it.I’ve used it and it works perfectly… However one side of the keyboard is cracked and the other one has a part of the plastic missing on the same . None of the metal on the keyboard is dented and all jacks work perfect. The keyboard comes with a volume pedal and a sustain pedal as well… Also included is an optional programming book which gives you detailed instructions on how to create your own sounds from scratch.

I make no promises but I’m still trying to locate a cassette tape that’s coded for different sounds such as organs and pianos… Also I may find the cord which attaches a cassette deck to download the sound as well. if I find those items I will include them for free but at this point I’ve priced it without the items in mind.” Click here to visit listing on eBay

Yamaha TX216 with 4 Yamaha TF1 Modules

“Used Yamaha TX416 (4x TF1/DX7 Modules) Vintage FM Synth. This is basically 4 DX7 modules in one unit. Each TF1 module has an XLR output and in my opinion has a much cleaner and denser sound than a DX7 1/4″ non-balanced output. All of the electronic components (audio/MIDI) work great.

All of the TF1 modules work as expected. The original batteries on the TF1 modules are soldered directly onto the circuit board and are a pain to replace, so I’ve soldered some handy battery holders onto each of the four modules (see last pic) for much easier battery replacement (batteries are used to store the current patch selection so when you boot the TX416 up it retains memory of selected patches).

I got this thing used several years ago in its exact condition, as you can see the case has quite a bit of wear on it, including light scratches and marks, and there are some missing screws on one side of the case but it is not loose in any way, the current amount of screws keeps it snug. The pull out menu/guide is also quite worn out but all the instructions are legible.” Click here to visit listing on eBay

Yamaha DX7

“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
