Yamaha CS-80 Synthesizer SN 1474

via this auction

"This unit is of later production (SN: 1474) and is very stable and in great shape. The only issue is with three adjacent keys: C#, D and D# 5 (upper-most register): These notes play as they should, but the aftertouch is intermittent and the volume is occasionally louder as compared to the rest of the keyboard. This may be a problem with the pressure sensors underneath those keys, a wiring issue, or an issue with an associated logic chip. Other than that, there are no problems with the synth; it sounds fantastic after it warms up, and all 8 voices (16 really) blend with the expected fatness! All features, sliders, switches, presets, etc. work as they should."
