Lot of 2 Yamaha DX11 Project Machines

“2 x Yamaha DX11 Synthesisers.

For spares or repair

I bought these two keyboards separately both in poor condition. I stripped each one down and cleaned them extensively, including cleaning each key one by one and polishing them before refitting. The bottom DX11 had about a dozen broken keys which I replaced but if you look closely you can see some are a slightly different shade, but I think this is better than having broken keys that don’t work.

They are both in very good condition, one is missing the bottom rubber feet

Unfortunately they both don’t quite work properly. They both power on.

The top keyboard seems to work quite well but button no. 15 doesn’t work (you can replace this, or it might just need a good clean with deoxit), and the top key does not sound. I suspect this is due to the rubber strip under the keybed not quite positioned right, I kept trying to move it a bit but couldn’t get it to work.

The bottom keyboard I can’t get it to make any proper sounds, all you can hear is quiet nasty digital noises, so I suspect this is a chip that has gone bad.

Upon testing them before listing them here I came across the above issues only. But months ago when I tested them I remember one kept cutting out and powering off and on. ” Click here to visit listing on eBay
