Yamaha DX100

“Yamaha DX100 Digital Synthesiser Keyboard. Great little FM synth in excellent condition. Comes with the original manual, voice programming guide, Play Book and a power supply. There are a few minor cosmetic marks but nothing significant as you’ll see from the pics. A lack of spare time means I never get to play with it so I’m looking for a new home for it. ” Click here to visit listing on eBay

“The keyboard is in good working order, I’ve used it many times, but it’s time to move on. I’ll include a power adaptor. Included with the keyboard is a rather nice bespoke case. The previous owner had it especially made. It’s lined with golden fur and the keyboard fits snuggly inside. The case is a little worn with use, but functions well. It’s a shame to let it go, but as I say, time to move on.” Click here to visit listing on eBay

“Here is a Yamaha DX100 Keyboard Synth can run on battery power for being mobile or by included adapter power. It was used live for playing that thumping keyboard bass or screaming lead synth parts and everything in between! Condition is used. I will throw in a guitar strap for portable play! Adapter is included!” Click here to visit listing on eBay

“This might be an easy fixer upper, I think a battery replacement and reset is all it needs. But I can’t guarantee anything.As-Is

Basically a mini DX27.

Sometimes it starts up and functions fine and makes sound, other times it starts up and freezes, or displays gibberish. Overall the condition is okay, everything feels solid, no broken plastic, but it has a lot of scuffs and scratches. All keys produced sound although F#4 occasionally didn’t. The headphone output is kinda scratchy. Battery power functionality is untested. But it powers on with a power supply (not included) ” Click here to visit listing on eBay

“Yamaha DX-100 synthesizer in very good condition for its age.

Since i have owned this I have:

1. Replaced the internal CR-2032 battery, adding a battery holder for easy replacement in the future.
2. Performed a factory reset.
3. Cleaned and refurbished the keybed.
4. Replaced the Volume and Data sliders/potentiometers.
5. Fitted third party slider caps to replace those missing.

All keys, sliders and buttons function correctly.” Click here to visit listing on eBay

“This unit is in good cosmetic shape but needs some TLC to bring back to it’s former glory. All buttons/keys/sliders/wheels function 100% but the output is low and fizzy. Also, the screen has a weak display and is somewhat intermittent. I’ve inspected the circuit board and couldn’t find any obvious issues — no leaky caps or cracked traces, etc. I suspect that it needs a recap. In any case, seeing as I already have too many jobs on my bench, I’ve decided to let this one go.” Click here to visit listing on eBay

“What can I say? It’s a great machine, especially if you like that clean 80’s sound. It is super capable of whatever wacky modified FM synthesis sound you want if you modify the settings. That’s pretty involved, but I printed out the manual for you so have at it. It does not come with the power cable, you can get one online or use batteries – I used a universal adaptor and it worked fine.

It is in pretty nice shape. I wouldn’t put it in a museum, but maybe I would if it’s the last one. There are no deep scratches, just surface stuff and wear from normal use.

Did I mention that it’s designed to use with a strap? Fulfill your rock star dreams like never before! They conveniently put the modulation and pitch wheel so you can use them while tearing up all 49 keys, or even just a couple of well chosen keys specifically chosen for your application. It has MIDI stuff on it – I never tried it, I assume that it works. There are a lot of buttons. A whole lot of buttons. It’s capable of some serious geek rock, smooth jazz (especially with the breath adapter {which I don’t have included}), or something fresh and new, ready to connect deep with people’s souls. Or funk bass lines, I hear it is known for that.” Click here to visit listing on eBay

“Hey guys, on offer here is my broken DX100.
You get what is shown in the pictures. There is no AC Adapter included.
I had my technicians try to repair it, but it was not successful. As you can see, 5 of the IC’s have been replaced with sockets and new chips.
You get all the original IC chips and the new ones I had replaced, including the DX-100 ROM and the 2 RAM memory chips, and a couple others.
I will ship it with four of the back screws installed, but all of the rest of the screws in a bag.
Hope someone can get this working, the display was showing garbage. Sometimes it could make sounds, but not stable. The power on self check was
showing cassette error, so I had focused on replacing the chips related to that circuitry, but no luck.
And I did replace the battery attached to wires now, as shown.
Cosmetically, the unit is pretty clean, as I was the single owner.
Good luck.” Click here to visit listing on eBay
