“You are bidding for my DX7S which is in superb condition for it’s age and is fully working. The DX7S is an improvement on the original DX7 and has a slightly cleaner sound due to improvements in the circuitry. There are also several additional useful features such as performance memories and micro scaling. It has recently had a new memory battery fitted in a battery holder to make subsequent battery changes easier.” Click here to visit listing on eBay

Here is my Yamaha DX7S Synthesizer up for auction.

I have replaced the internal battery with a new battery housing soldered onto motherboard which will make future battery changes a total breeze!

The initial factory sounds were lost due to ths battery so it will need the sounds loading back in or a cartridge, I don’t have the cartridge but it can be done via midi.

This is a vintage synth in great condition that needs the sounds loading boack in, all keys and case in great condition… grab a bargain with a .99p start and no reserve.” Click here to visit listing on eBay

“Additional Info: This synthesizer is being sold as is without a cartridge. The synthesizer has been sitting for a while so it could use some general clean up. One of the faders is missing its knob (see pics) but still moves up and down. The synth may have low battery as when we plug it in it does power up and kind of sounds. When we try to play it it seems like it wants to play and makes a static type noise with a very faint sound so it will likely need the battery tested and potentially replaced. The bottom plate is missing multiple screws (not included) and it is loose. ” Click here to search for synths on eBay

“Yamaha DX7s Keyboard Digital Programmable FM Synthesizer with Original Cartridge

This keyboard has had the onboard battery replaced with a new separate board isolating the battery from the rest of the circuit board. I read up on it enough to know that the coin battery had a propensity to leak which is why I replaced it with a separate coin battery holder and while I had it taken apart I took the opportunity to clean all the crud out from under the keys and even replaced a few.

The pictures attached show close-ups of the front the keys which are all mostly level. I suppose you could adjust the felt underneath one or two of them if you want to get them to a more precise level.

All 50 of the sound banks work though buttons 14 and 15 require a little more pressure to switch. I cannot test programming because I have no MIDI setup as I am not a musician. One of the reasons I originally wanted to sell this locally was that whoever bought it could test it out before committing to the sale.

The pitch wheel moves the notes up and down as I might expect but the modulation wheel does not appear to do anything noticeable to the note when I move it with a key pressed down. I don’t know if it has to be programmed or if the effect is only on certain sounds or maybe I just don’t have the ear to detect it.” Click here to search for synths on eBay

“Here’s your chance to allow me to thin out my vintage keyboard collection, and my loft insulation, and for you to benefit from owning a classic bit of 80’s kit at the same time!

Up for grabs is this original 1987 Yamaha DX7S, in full working order, and with the original factory patches installed.

I have owned this synth since new, and in that time, it has never missed a beat.

Cosmetically, it is in very good condition, with only a couple of marks. All keys still play perfectly, velocity and aftertouch work as new, and the semi weighted feel is very even and reliable. The display is still bright and legible after all these years.

The only reason I’m selling it is that I have 10 other keyboards in the collection, and very little space to actually set them up to play – so in preparation for that inevitable point in time where we “downsize”, I have to make a tough call.”
