“Vintage 1970’s ElectroComp EML-200 Modular Synthesizer, in blue.
EML 200 is keyboard-less, making it more like an Expander module designed to interface directly with other EML equipment. Most notably, with the Model 300 manual controller which offered a 4×4 key matrix, pitch knobs, and an oscillator with envelope generator and VCA of its own. Today, you can use the 200 with analog synths other than EML with the properly modified CV/Gate connections and converters (its oscillators are a non-standard 1.20v/oct).
It does power up and the red power light is on in the pictures.
Overall in very good shape, with some scratches on the sides and back panel.
I did have them checked out, and had the necessary repairs\cleaning done to make them functional.
The unit was cleaned and tested. All the jacks, connections, and potenciometers were cleaned and checked.(Per the repair technician)
The sample and hold were repaired on this unit.
All original.” Click here to search for synths on eBay

“1980 Moog Opus 3 Vintage Compact Analog String Synthesizer + Gator TSA Hard Case
“Roland SH101 with boxed mod grip and choice of-leather strap in mint condition, you will not find a better example on the market.” 
“Original Moog Opus from 1980. In good working condition, strings are a little quieter and the pitch shifter is a little scratchy. (I have videos I can send to show what I mean) Some wear on the sides and the chorus selector switch is missing its cap. (Pictured)” 
“The synth is in quite good condition for its 40 years age but for the following.
“Moog Prodigy Vintage Analog Synth. Comes with original Moog gig bag and original Moog box. The synth is in excellent cosmetic and working condition. Only selling it because I am not using it, it is just sitting there.” 
“Moog Minimoog Model D Vintage Synthesizer. Minor scratches. Stored wrapped in a blanket and untouched for decades.” 
“Nice condition! Everything works. Please see pictures. Comes with a Moog suitcase bag! This one is not missing any white or black knobs like some of the other one’s for sale and it doesn’t have any extra holes drilled into it. All original condition!” 
” 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.” 
“1973 Old Osc Board Model D Serial 3609!!!!
“Tested and working well. ” 
“SH101 AND Bonus *Roland A-01 Sequencer with CV gate AND MIDI connection a perfect pair to marry all MIDI and CV gear under one roof!
“This SH2000 has the Sum (or Sigma) mod, this means you can combine all of the preset switches in any amount and any combination (normally you can only use one switch at a time). This opens up an incredible depth to the instrument’s range and customizability, the tones you can get out of this thing when it starts stacking all the oscillator’s waves through its gorgeous filter are insane.
“Roland’s first synth EVER, truly a museum piece.
” For sale is a Roland SVC-350 in good shape and fully functional. Classic analog vocoder. Everything is working as it should, check out the pictures to make sure you like it. Will be safely packed for shipment. Includes pictured rack case. ” 
“Hey, eBay! Up for grabs is an untested Roland Compu-Music CMU-800 analog synthesizer / drum machine rack module for Apple II, IBM PC, and Sharp MZ-80K computers. Listed in “for parts or not working” condition as power LED does not appear to light up when plugged in and switched on. I paid $125 (+S&H) for this last year, so offering it here for the same amount as I have no way of testing it. No manual, literature, packaging, or interface boards included. “
“Used, great shape for it’s age. I had some problematic sliders replaced. Pitch bend potentiometer has to be nudged into center sometimes but didn’t bother me enough to have replaced when I took in for service. As with all analog synths, pitch can drift while warming up .” 
” Roland JD 800 synthesizer in great condition. Fully functional. The keybed was replaced by the previous owner prior to any red-glue issues. I have over-written a number of the original factory patches so you will need to perform a factory reset if you want those patches. Condition is Used.” 
” I LOVE THIS SYNTH! I cant believe I am letting it go… This is a vintage synth so please understand the caveats with buying something 30+ years old. Some of the sliders might be a little scratchy and some of the keys might not respond as intended. ” 
“Here you can bid on a pristine Roland CR78 Drummachine. As you can see by the pictures, the optical shape is really, really nice. Not much signs of use, on the front in fact no signs of use.
“This is a fully refurbished Roland Juno 106 and it’s in excellent condition with one scuff as pictured, but it can be cleaned up with a magic eraser. The work was done by Bell Tone Synth Works, if you don’t know, you better ask somebody about them, but they do excellent work. The list is below. Why buy a Juno 106 that “works” now and may break very soon, when you can buy this one that you KNOW will give you years of trouble free playing. ” 
“Selling my beloved Sh101 will be sad to see this go but need the funds and will no doubt get another in the future. This has been recently serviced. It does have a little chip in bottom corner but this does not affect the sound or has caused any internal problems ! ” 
“For sale is my Korg Delta synth /string machine . The unit is 35 years old and is in fantastic condition for its age .. there are a few small marks here and there which is to be expected for equipment of this age.
“Yikes! This one clearly saw some action.. I got it, in much the same state, off Vemia maybe 10 years ago.

Some small scratches, but nothing significant. works perfect and battery compartment is clean. (fresh batteries). No A/C power adaptor or case.” 
“This is a vintage Korg Poly-61 synthesizer. The Korg Poly-61 exhibits pinholes on a handful of the lower octave keys made by the previous owner. Not sure the intention or purpose of these holes but nonetheless, it is not affecting the playability or overall integrity of the keyboard. Also, each of the corners shows wear that is normal for a keyboard of this age. Overall, the Korg Poly-61 is in very good condition. The Korg Poly-61 is fully functional and operates as intended.”
