via the seller: "This Minimoog Model D is truly a rare find. Built in 1976, Serial Number 5699. I have owned this unit for well over 30 years. Very light use, and extremely well taken care of. ALL switches, dials, controls are fully functional and have ZERO static. The three oscillators are in perfect condition and well tuned. All waveforms are perfect. Glide, decay, sustain, cutoff frequency, filter emphasis all sound like a dream. Pitch and Mod wheels are a clear lucite material. This unit is fully functional and is in great condition. However, it does have two issues. One cosmetic (the very edges of B3 and C3 keys have a very small chip on the surface,), the other electronic (keys G3-C4 have an intermittent issue where they sometimes all play the same pitch as G3.). Both issues can be easily corrected by servicing the unit. I am not an electrical engineer so I didn't feel I could fix it myself. The asking price has been reduced by $500 to compensate for the cost of the repairs to the unit if desired. Other than those two minor issues, the unit is in fantastic condition. SUPER CLEAN control panel and the wood cabinet is intact with not a scratch on it. The winning bidder will own one of the best preserved original Minimoogs available today."
