Siel DK 80

“Used Siel DK 80 FM Synthesizer. From 1985. Very similar to the DX-7 Yamaha. I used this for a few years and it always worked well. Pulled it out of storage yesterday (a temperature controlled bedroom in my parents house) to test before selling and it doesn’t seem to work anymore, however. The unit makes somewhat loud (relative to the sound of the synth sound) buzzing sound, or the synth level seems quite low. Also, the synth doesn’t seem to want to change programs but honestly maybe that is simply because I can’t quite remember what to do to make that happen!” Click here to search for synths on eBay
