“This one is in excellent condition and working 100%. It has just been professionally serviced and with quite a bit of restoration. As the title says, this is a muSonics Minimoog which are rare and seldom come up. This model has several similarities to the RA Minimoog. Besides the metal face panel, clear pitch/mod wheels, squared back panel and walnut cabinet, the oscillator board, as well as the rest of the boards are all discrete. Many will describe the next generation, CA3046 oscillator board as the first board (I think they mean the most common and earlier board to the UA726 board.) The serial numbers from Minimoogs around this time were written with ink, not stamped, and have often worn off. You can get a close enough range by looking at the oscillator & filter boards since they generally have serial numbers written on them. The oscillator board shows #1219 and the filter board shows #1221. I have owned many RA & muSonic models over the years and this would be accurate. It It will be properly packaged when sold and will arrive in the condition as stated. Not sold as-is! Proof of the actual shipping cost will be provided if needed.”

” This is a vintage Moog Minimoog Model D that I think is from around ’73 or ’74, it is serial number 1599, which I am told means it is number 599 made as the serial numbers for the Model D began at 1,001.
“Up for Sale is English keyboardist and violinist Eddie Jobson’s Minimoog Moog Model D keyboard. Eddie was known for his use of violins and synthesizers. He has been a member of several progressive rock bands, including Curved Air, Roxy Music, UK., Jethro Tull and YES.
“I’ve owned this keyboard for over 30 years. Cosmetically it is in fair condition it is in good working mechanical order.
“This one is in beautiful cosmetic condition and working 100%. It is ready to be played and needs nothing! This is an original Model D and not the reissue. Serial #4527 (built in 1974). It has had quite a bit of internal & cosmetic restoration and likely more than any other here on Ebay.” 
“Moog model D in good working condition. Recently cleaned and repaired by Speed of Sound (see photo of receipts). Comes with carrying case. Boards with handles for easy lifting are attached to frame. There is a small crack in the wood frame.” 
“The external physical condition can be seen in the attached photos. There are no cracks or loose joints in the case and the instrument is very sturdy. Oscillators 1, 2, and 3 bleed through the headphone output. There is a constant background drone. This does not come through the main output and does not affect performing or recording. After warming up and being played for an hour or so most of the keys are stable. Some of the upper octave keys will go unstable and the frequency will fluctuate from time to time. Most switches and pots are scratchy when flipped/turned. Sometimes the main output switch does not work. If you turn if off and then slowly turn it back on it will work. I worked with the instrument for 3 hours yesterday and set all the internal pots from the rear panel and those are the only problem notes I have. There is a somewhat loud key-click, but that is not heard in the output, and would not be heard during a performance or a recording session. Also there is one yellowed key. That was a replacement key from the 70’s that yellowed over time. (According to the roadies they did not know what happened.) The thing sounds absolutely awesome and playing it brings back memories of past gigs and of hearing Keith Emerson or Rick Wakeman back in the 70’s.
“Being perhaps the most popular version of one of the most iconic monophonic analog synth series of all time is no easy feat, but the Moog MiniMoog Model D manages to pull it off. As one of the first non-modular synthesizers, the MiniMoog Model D is highly intuitive and requires very little knowledge to use. The model D boasts contouring circuits and three separate, completely original oscillators, one of which can be used as an LFO. Although the Model D was reissued, the ’70s MiniMoog Model D hasn’t depreciated in value, desirability, or style.
“Fully functional. Recently serviced. There are cosmetic dings and scratches on the wood and some very minor defects on the face plate, but nothing unexpected from a unit of this age. All parts appear to be original except perhaps the power plug and the washer around the headphone jack. The larger washer is there to conceal some cosmetic marks around the output plug.” 
“Original Vintage Moog Minimoog Model D + Kenton box. SERVICED!” 
“Moog Minimoog Model D Vintage Synthesizer. Minor scratches. Stored wrapped in a blanket and untouched for decades.” 
” Minimoog model D from 1974. Plays and sounds as it should, and with the Opto-Key modification, fussing with the old style keyboard contacts after they oxidize and go bad is no longer an issue. If you got in touch with Chris of http://www.thisoldsynth.com/index.html , he would be able to install a MIDI connector kit for it if you’d like to have that. The wood is in good shape, the previous owner has scratched his name and phone number into the metal case, the rest of the metal has some scuffs and stains, the power lightbulb has burned out, and the headphone output volume knob is very crackly (this has not affected my use of it since the other two main outputs work just fine). Every other knob, pitch/mod wheel, and switch functions correctly.”
