DK80

“Listing is for both synths—if you want just one send a message I may consider it.

Picked these up and they were supposed to be both working. At first I thought this might be true because the first one I tried does make sound normally, but as I tested them more I realized they are both broken. NOTE: I had these in storage for a bit and when taken out I noticed they still have a smell of smoke from previous owner. I’ll try to wipe them down but keep in mind it may take more than that to get rid of the smell. Also—they both share a weird custom power supply which seems to work fine but uses what appears to be a midi cable connection?? Very mysterious but it works.

Synth 1: all controls and buttons work and makes noise Except the second DCO does not work, the noise control also doesn’t work, but interestingly some presets will have noise added but it’s usually too loud, and just sounds a bit weird or sloppy. As is can get many tones out of it, but only 1 DCO per voice. Filters and stuff work with no issue.

Synth 2: turns on and seems to respond to all buttons on the screen but can’t hear any noise at all. Also has two keys which stick up as seen in pictures.

Cool sounding synth, I wish they worked but as is I don’t know what to do with them.”

“Collection only please due to weight, and I haven’t got a box that is be able to fit it in.

Never gigged with only home studio use.

Please note this is working fully as a midi controller, but currently has no sound, it looks like it could just need a new battery after some Internet searches, but not that technical so don’t know.

Siel DK-80 Vintage Synthesiser 1985 Very Rare!. Low serial number of 3780, so was one of the first to be produced of this synth.

It’s 12 note polyphonic, velocity sensitive, the modulation wheel doubles as the pitch bend with a button press, you can reprogram some of the presets, I can’t remember how many possibly 10. If you know the Ex80 the expander version it’s basically 2 of them bolted together with a lovely feeling keyboard.

Works fully as a midi controller, with hardly any marks, especially since I bought it in 1985! That was the year it was made as well.

So there’s a few scratches underneath and a few of the screws could do with tightening and glueing, main problem is it has no sounds, apparently that could just be the battery, as I’ve had it done before and it worked, but I believe it’s soldered in. Quick fix if it’s just that and can do it.

Broken key as in photo – looked at replacing it, as a key on here is about a fiver, but as I’ve broken my shoulder just haven’t got the strength to do it, as its a heavy keyboard.

Oh the cartridge slot has had a spot of superglue on it to keep it closed as the spring needs repositioning or replacing, not a problem really if you haven’t got a cartridge.

Comes with case, black and red, new USB cable and PSU as apparently not many have them anymore.” Click here to visit listing on eBay

“Dispatched with Other 48h Courier.

2 Siel DK80 synthesiser keyboards.

Both untested as I cannot find the power supplies so listed as spares/repairs.

One of these worked for sure but its been a few years since I tried.

The other was bought cheap without PSU and was untested as the power cable is cut off.” Click here to visit listing on eBay
