Yamaha DX7

“This DX7 is for parts/needs repair. The keyboard powers on and passes signal, you are able to switch through presets, adjust algorithms, and parameters, however, the keyboard seems to have an internal tuning issue. Even when adjusting the master tunes, certain keys seem to always be out. I do not know what is causing this issue and have troubleshot the problem to the best of my capabilities. Other issues with this keyboard is Volume fader knob missing, a minor chassis spilt on the left side, and a slightly loose D 3 key. Selling as is” Click here to search for synths on eBay

Yamaha DX7 II FD

“Here is a classic DX7II-FD. This synth is in good cosmetic shape other than the damage that was received while in storage. Some heavy items were placed on top of the keyboard, resulting in damage to the bottom two octaves of keys, and to four of the buttons (two of the voice mode select buttons, the EG Copy/Store, and the Play/Performance button. I’ve been playing the synth all morning and it still sounds great. All of the other controls seem to be working just fine. Please see the photos to examine the damage.

This is a legendary and fantastic sounding synth. I’m reminded how good it sounds… and how much better it sounds than the emulations that are out there… today as I’ve been playing around with it. These are always pricey to box up and ship, so local pickup in the Lehigh Valley or NYC area is possible.”

It looks like something has burned out on the mains input circuit board, its probably not called that, sorry i dont know much about these things. Im certain this is an easy fix for somone in the know. The Synth is in worn condition but everything worked perfectly up until it decided to catch fire. Well it did smell like that !!

“Very good condition, one owner, mild use, smoke-free, and fully functional except the battery needs to be replaced. All buttons are functional and none have cracks from overuse. Because the battery is dead, I loaded sounds into the on-board memory to prove that it is working properly. If loading sound banks via MIDI, the battery is not needed. Battery replacement procedure is fairly straight-forward and can be found on YouTube. There are minor scuffs and scratches on the bottom but nothing serious. Cosmetically, this item is in really good condition. I’m selling only because I have to downsize.” Click here to search for synths on eBay

“According to Ray at Fair Deal music in the Bullring,Birmingham, where I bought this c.1990, this Yamaha DX7 used to belong to TheDamned.

As you can see in the photos, there’s some cosmetic damage to the metal on the right-hand-side; apparently caused by a lamp directed onto the keyboard whilst on tour. There are some other battle scars: the slider buttons are missing; some of the plastic above the control buttons is scratched and cracked. Someone has scrawled ‘MIDI’ next to button 8 and crossed out the brown ‘Function’ button; possibly Roman Jugg or even Captain Sensible. Who knows?” Click here to search for synths on eBay
