“¡This is a MUST OWN keyboard for any serious Detroit Techno student or enthusiast! Totally awesome DX-100 with fresh battery and complete factory reset. Includes power supply. Definitely a few nicks and scruffs but all text is legible and all buttons work. Selling because I own two and only need one.” Link

It’s in full working order, comes in its original box (including polystyrene cushions), has original power lead, original play book, owners manual and voice programming guide. Even the power lead has its original box! The only non original part is the headphone jack converter (I bought new especially for the new very lucky owner)”
Spares or repair faulty.
Turns on with power supply and batteries but display is blocky and doesnt work.
the base is loose and missing screws.
no power supply included.

” Im selling my Yamaha DX100 with a compatible but not OEM power supply. It works great as a midi sound module, which is how I’ve been using it, but does have some issues, so I have to list it as for parts/not working. But it DOES WORK, here are the issues:
-1 key is missing (refer to photos)
- about 6 lower keys are hard to trigger but they trigger when pressed hard. (it definitely seems like they just need their contacts cleaned)
- 1 strap button is gone, leaving a small hole on side of synth. (refer to photos)
- Output jack is scratchy. Headphones jack works fine though.
- Since the power plug is not the original, the jack itself seems like it might not be long enough so it sometimes cuts out when moved. ” Link

“Yamaha DX-100 Keyboard Synthesizer
The keys on this instrument are smaller than normal. 49 note keyboard is 22 1/4″ long.
The Bad: High c note (last note on the keyboard) does not work. The rest of the keys work fine. Footswitch jack has been removed, probably because at some point the output jack needed replacing so I switched them out. The plastic section of the case between the pitch and modulation wheels is broken so these controls wobble a bit but they still work. The Good: All functions work OK. RAM Memory battery inside has been replaced.
There was some Battery leakage in the Battery Compartment which I cleaned up.
A fun little instrument with a lot of different useful interesting sounds and functions.
Comes with power supply and Soft case and three different manuals to help you figure out how to get the most out of it.” Link
“This is a Yamaha DX100 FM synthesizer that I’ve had since about 1999 and is in overall excellent condition. There are a few scratches on the bottom from normal wear but the display, button, sliders, midi jacks and knobs are work fine. There is one key (middle E) that clicks when depressed but it is still functional and other than that all keys work perfectly. No battery leakage in battery compartment. This does not include the A/C adapter.” Link
“Classic vintage Yamaha DX100 synthesizer with Zapp talk box patches loaded in the sound bank. Comes with all original manuals, it was used for talk boxing and it sounds beautiful.” Link
8 of key contacts need cleaned
Cord not included” Link
The only flaw is by the rotating knobs a small piece of the casing is broken off, but does not affect the keyboard in any way.
Has 24 internal programs, plus four more banks (PB#s), lots of sounds and you can make changes to any sound and save it.
Lots of info online about this keyboard, please find answers to specific questions as I may not be able to answer programming questions. I simply used this to support sequencing projects in the early 90′s. Average use, clean item. A few scratches on bottom casing do not affect performance. Works perfect and without any issues.” Link

“Yamaha DX100- Good condition, rarely used. Has been packed away in a closet. Missing both slider knobs. Includes original charger that came with it.” Link
Used ’til the mid nineties in a home recording studio, then put into dry storage.
The battery cover is missing, and I do not have the mains transformer.
The screws that hold the front to the back are also missing.
Tried to recommision the DX100 a couple of years ago, but it seemed to have developed a number of faults.
I tried to power up using the mains adaptor, but without joy.
Subsequently I managed to get power to the unit from a new pack of batteries.
The various buttons and keys seemed to be working okay, but the digital display was not.
There we have it, a DX100 sold for parts/ not working as there are many known faults,
and I cannot guarantee its current working condition.
Having said all that the unit looks very clean and tidy, with all buttons and keys intact and very few marks or blemishes.
Thanks for looking.” Link

Physically it has rust on the strap connectors on both sides of the keyboard, scratches visible under light, dust/dirt in grooves and generally needs a good clean. The battery bay appears clean and the screen only has a few hairline scratches visible under light.” Link
“Unit Powers up but function keys 1 – 16 do not work, 17 – 24 seem to work ok Keyboard has issues – there are dead keys and some keys play 2 notes (all C# keys play C# and D, all E play D# & E, D & D# keys are dead) I replaced 2 burned resistors (100 Ohm 1/4 watt each) that fixed a minor issue but it did not alleviate all these other problems.” Link
“This auction is for a Yamaha DX100 keyboard FM synth. This is a 4-operator FM synth similar in some ways to the classic DX7, and has a four-octave mini keyboard and attachments at either end for a guitar strap, so you can wear it during live performances if that’s your thing.
The auction includes an AC adaptor. Batteries (and cat and Bart the Parrot) not included.” Link
I found issues with buttons 2, 8, 9, and 10 not working or could possibly be stuck.BC1 Sax and BC1 Harmonica possibly needs programming. Some scratches, mostly on the bottom and a small chip off rear near wheel is missing (as I illustrated in the photos). If there is anything that I missed it is not intentional. This was one of my favorite keyboards and I treated it with loving care as all of my equipment. I hope that you enjoy this amazing synthesizer as much as I have.” Link
