"With its controller, and exceedingly rare cartridges, this Prophet VS is a very clean example of a pretty hard to come by synthesizer. It was recently given a clean bill of health by one of our in house techs, and it sounds excellent."

Electronic Music Laboratories Electrocomp EML-101 SN 475
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing
"This is a very rare Electrocomp 101 (Serial # 475) in a very good condition. It has been fully serviced and has no issues whatsoever.
I'm the third owner of this unit. Some mods were done in the 1970's by John Phelan, one of the engineers @ EML which makes this unit totally unique. Here's the functionality of the added 3 switches:
The switch near the Glide Control, multiplies and lengthens the glide time as the pitch slides from note to note. The switch below the filter turns the BP (bandpass) filter setting, into band reject (meaning it provides highpass and lowpass filtering simultaneously).
The switch next to the mixer changes the character of the noise (from white to pink)
I took great care of the unit and used it only in my studio. I'm selling it because I'm simply not using it at all. This 101 comes with original manual and documentation."
Note SN 475 was listed back in 2014.

"Am extremely sad to sell my Steiner-Connolly Synthacon
This was handmade by Robbie Connolly (The Killers) and his team under the direction of his neighbor Nyle Steiner who built and designed the original Steiner-Parker Synthesizers in the 70's. Made with real through hole circuitry and manufactured by a small team in Provo, Utah these are as luxury of a synth as you can get.
I had the pleasure of working on their team which is where I earned this, but now must part ways with it to pay off some debt.
I am really not eager to part with this, so it's priced accordingly...
Everything works, no visible imperfections I am aware of. Been kept in my home studio.
This is serial number 10, and I am unsure as to whether they're making more of these or not..."
