“Yamaha DX27 Programmable Algorithm Synthesizer Ser#020043 Needs Adjustment
Additional Info: This synthesizer is physically in good shape and looks to be mostly in good working condition. The low C key on the synthesizer does not function and the data entry dial is missing its knob but still moves up and down (see pics). In testing the synthesizer we found that the output jack and the power jack are sensitive to the angle that they are connected by. We turned the synthesizer and got feedback and the synthesizer flickered off and on. You will likely want to have these adjusted so that you do not need to worry about getting feedback while playing.” Click here to search for synths on eBay
