Sequential Prophet 600

by

“This synth was recently serviced by Wine Country in California and is working very well! All functions are working as intended. A brand new membrane panel was installed so all pushbutton keys are easy to press and reliable. The synth was fully recapped.

The key bed was also cleaned and all keys are working well with minimal dropped notes as long you don’t play with a very light touch.

A print out of the manual / service manual is included in a binder, along with the Wine Country program patch cassettes and the original faulty parts they pulled, along with the original CPU chip that can be reinstalled if you would prefer to revert the Prophet 600 to a non-gligli “stock” condition.

The synth will be packed very well and will ship with full insurance.”

“This
Sequential Circuits, Phophet-600, Original MIDI,
synth has seen many days on the road,
and has a broken “A” key that can be replaced for about $15 overseas,
all original equipment from 1982…

The sounds from this unit are the same sounds you get from the original Prophet 5, but under MIDI control, for complete freedom of expression…

This synth comes WITH the heavy-duty road case for secure travels, and shipping…

I don’t have the time or money to work on this anymore…

I will supply you with the technical manual for troubleshooting problems…

All the parts are there, it just stopped working, and I don’t have my test equipment anymore…

Thank for taking this off my hands… :)” Click here to visit listing on eBay

“Sequential Circuits Prophet 600 w/ GliGli mod, latest update and patch set.

I’ve owned her since 2012 and barely touched her. She has been fully serviced in preparation for sale, with the latest GliGli patch and Luke Neptune Prophet 600 patch pack installed.

Perfect working order and good aesthetic condition (the odd scratch and a chunk out of one wooden cheek – please see the photos). My tech replaced an encoder pot and likely forgot to cut the post down – so that knob sticks out a few additional mm compared to the others.”

Sequential Circuits Pro One Project Machine

by

“Vintage Sequential Circuits Pro One Synthesizer. Unsure if item works therefore selling as is. May or may night work or need repair. Vintage 1980s synthesizer.

UPDATE 8/28/22

Been getting alot of questions so I took more pictures. This is my Pro one. Bought it new in the 80s at Sam Ash in Queens NY. Used it a few years at home only. It has been unused for over 30 years in storage at different locations. When I used it, it always worked. Looks like the fuse has fallen out and I don’t have another or know when it was lost. I’m assuming that’s all it needs but not sure” Click here to visit listing on eBay

Sequential Circuits Six-Trak

by

“This is a joy to own but alas I cannot do it justice. Classic sounding from a time long long and they do not make them like this anymore. Studio use only and recent repair and upgrade.

Looks great with the odd mark and scratch which is to be expected. power is direct from the back to the plug. I have also printed out most of the manual (it is not the original). The joy of playing this is that it is 6 Note poly which was a rarity back then. Most of the tech spec is on line but if you are looking at this piece of history you will know all about it anyway.” Click here to visit listing on eBay

Sequential Circuits Pro One

by

“Sequential Circuits pro one.

I bought this fantastic sounding mono synth about 20 years ago second hand.

The power cord is somewhat frayed where it meets the machine, but this causes no problems as yet in turning on the machine.

Also, the keyboard has some dust in it meaning that sometimes, if pressed hard some of the inputs on some keys stutter, due to the electrical connection.”

“Don’t ask what is wrong with this item. 🙂 LOL

It is not too good to be true…My family is simply selling at a lower price than it is worth because we need the money and need to downsize…

This is in perfect working condition. Cosmetically, as you will see, it is really good for being over 40 years old!

Recently, it was opened up, cleaned out, including every contact. Built like a tank.

All keys work perfectly, and all knobs as well.

The is amazing what sounds can be created with this thing.

Anyway…

** It Comes with the Power Cord, and will be packed safely.” Click here to visit listing on eBay

“Fully functioning and restored – Sequential Circuits Prophet 600 Synthesizer Vintage Restored not Prophet 5. I am not a musician or a keyboard player. History of this instrument as I know it…This synthesizer has spent its life in a padded hard case. It was given to me by a co-worker back in 2013. He purchased it from Goodwill online. (However owned it prior to that took exceptional care of it.

The unit was not working and I held on to it since then. I decided last year in March to have it repaired. It would light up but not boot to program mode. I sent the unit to one of the absolute best technicians possible for this type of instruments. The unit was sent to David Sesnak of Wine Country Productions in San Jose, California. He could not believe how great the condition of this unit was cosmetically. All repairs he made totaled $746. I had him install the GliGli update as well.

The wood sides are original. I’ve included the invoice of work performed. I could not bring myself to discard a vinatge piece of music history so I am offering for someone to enjoy for years to come. Buy pays actual shipping costs. Package is 31lbs and dimensions are 51L x 25 W x 8 H. Unit will be professionally packaged.” Click here to visit listing on eBay
