Scam alert below.
"100% operational EMS Synthi AKS synthesizer, a true vintage original from the early 1970s. It was bought about 5 years ago from a couple who had stored it in a closet for around 30 years. Everything works: no scratchy pots (except for a slightly scratchy reverb level knob) and no iffy sequencer problems. Just plug it in, make a patch and you're ready to travel the spaceways. Comes with an instruction book, all the original patch pins, connector cable for the keyboard, and of course the power cord. This has been described by many as being LSD in a box. It's really all that and more..."
Update: see the comments in this post below. I have no way of verifying so as always, buyer beware. The listing doesn't ask you to, but remember, never buy outside of eBay if a seller offers a better deal as you will have no protection if you do so - always buy through eBay's Buyer Protection. One odd thing about this listing is that the item location is in Monrovia, CA, United States, while the listing is for GBP. As for the images, I did a search on Google's image search and could not find them elsewhere.
Update2: See the second comment below. The wallpaper matches the background in the video of a previous post from "cores".
Update3: I checked in with Cores via his YouTube account. He confirmed these are his pics and he is not selling his AKS. If you are wondering why I verified, there are other scams to watch out for, particularly people trying to question the validity of auctions to keep bidding down. In this case we can no be fairly certain that the images in the listing are not from the seller. Why not 100%? Because anything is possible.
