“Juno 106.

This is working and still produces the wonderful sounds it is famous for.

It probably needs an overhaul. There are 4 keys that are not working; I have marked this in red on one of the pictures. Of course, if you play it via a midi connected keyboard, it plays perfectly.

Some of the menu buttons seem slightly iffy. I just tested it (after a prolonged period of non-use) and for example, some of the blue bank buttons didn’t work but soon started to after a bit of repeated use.

I dare say that an overhaul by someone who knows what they are doing might work wonders.

Also, one of the sliders is missing the plastic knob part although the slider still works perfectly. It is the “sub” slider and you can see it in the main picture.

Please note, this is local collection only due to size and weight. I could potentially deliver it depending on your location so please feel free to enquire.

Item sold as is – no returns.” Click here to visit listing on eBay

“I’ve worked on this synth myself and it’s completely at peak performance. It’s date stamped 1973 inside, which was the first year of its production, and it’s Roland’s first synthesizer, so it’s a piece of history!

When I got it, it was fully working but a few months later the divider chip failed. I replaced it with a New Old Stock chip I sourced from Japan, and I installed it with a plug receptacle, so if you ever need to access it again you can simply unplug and plug it, rather than de-solder/re-solder it. I don’t think you’ll ever need to mess with it again because it was replaced with an unused NOS chip, so I suspect it will last another 50 years or more. While I was going through it I cleaned all of the key contacts, which cleaned up a few notes that were double firing. It now works perfectly, as new.

I don’t think you’ll find a better example of this synth. It’s super vibe-y and the filter is magic. It has an early Low-Pass filter design, called a diode filter. These were only used for a year or two in the early 1970’s and they were replaced with cleaner designs, but there is something very special about the sound. When you push the resonance high you can hear the gnarly, gritty diode sound. And it’s more noticeable when the cutoff is higher, too. It’s much subtler when you have the resonance at more reasonable levels, or when you have the filter controlled by the ADSR envelope because the ADSR only pushes the cutoff up momentarily. Watch the first DEMO video (link above) on YouTube to hear it firsthand as I go through it.

It’s 37 keys, but there’s a L-M-H octave switch to add an octave on the top and bottom. It is a monophonic synth, so it’s meant for leads and basslines. It is killer for both!!”

“For sale is an incredibly rare vintage Georges Jenny Ondioline monophonic analog tube synthesizer keyboard. This model is believed to be from the 1950s and a unique transitional model due to cabinet design using real hardwood. This one has been completely restored with no attention to detail spared. Work included restoring and rebuilding the amplifier circuitry, keyboard, switches, and refinishing the wood cabinetry, with utmost attention to accuracy and playability. As expected for a vintage instrument of this age, there are still some signs of aging. This is likely to be the nicest Ondioline you will be able to purchase and find for sale. There is over 100+ tech hours involved in the restoration of this machine from two of the leading Ondioline specialists, primarily restored by Daniel Kitzig in Germany and assisted by Stephen Masucci in New York. This was restored in collaboration for Forgotten Futures, a non-profit set up by Wally De Backer a.k.a. Gotye, who is the leading authority on Ondiolines and passionate caretaker for preserving these beautiful instruments. You can read more about Ondioline history on Forgotten Futures Music.

This Ondioline is 100% fully functional and sounds fantastic. Ondioline’s are a very unique monophonic tube synthesizers capable of a huge range of expression due to the exponential volume lever to be operated by left knee in player’s sitting position, as well as large combination of tone controls through the sliders, the vibrato built into the keyboard (left/right movement) and the tap sensitive triggering ribbon. Add to the special expressive design the beautiful art-deco inspired wood cabinet housing and you have historic instrument that is as gorgeous in looks as it sounds.” Click here to visit listing on eBay

“Classic and legendary Prophet VS rack in full working condition with no operational issues… with original manual and printed schematics. So many synths and synth designers have taken bits and pieces from this design but nothing beats the original.. nothing sounds as bold and awesome as the original. The sonic possibilities are endless and the filters are classic Sequential. ”

“I have listed this Pro One as mint because that really reflects its condition, both in and out.

Only one previous owner and has been looked after extremely well. This particular pro one has been fully upgraded to modern specs including:

– New Fatar Keyboard (same as new pro 3)

– New Knobs

– Kenton MIDI Retrofit

These upgrades really bring the synth to a whole new dimension of playability and programmability, especially with added MIDI.

Aside from all of this.. it also comes with a hard flight case which on its own is worth over £100.

All pots have been cleaned carefully with contact cleaner and the unit has been claibareted within the last year, no repairs or service ever needed. Very minimal dust when the lid was open.

I would almost list this as B-Stock its that good, by far the best of all of them online at the moment. so buy with confidence in knowing that you’ll get years out of this classic beast. Will be dusted well before collection ;)”

” The Yamaha CS5 is great for analog bass and gritty sounds. A simple design, easy to use and still sounds great!

Due to the age of the synth there will be some natural wear on the synth as it’s been passed from owner to owner however, it is in good condition.

There are a few things you will need to consider:

1) The HPF/BPF works

2) The LPF works but;

a) when fully clicked into place, the sound is crackly/fuzzy
b) to get a clear sound however, you’d need to have it in between the LPF/BPF (hope that makes sense)

3) The plug cable is slightly loose but it is safely fixed to the instrument, so it just needs to be handled with care.

With all this being said, getting a service may be an option for you too at some point.”

” Here it is. I never thought that this day would come. This is the ultimate SP1200. This is the 2nd of 2 that I have owned through the years and this one was the best.

It is being listed as for parts/not working because of the vintage nature of the instrument in that they do have their quirks and will need tech-ing in the future and I do highly recommend a full service by someone like FORAT. That being said on check everything works as it should on last power up. I have a handful of floppies around 20 to throw in as well (people like the Lotherak SD card thing, but I’m telling you floppies is where its at, nothing like sharpeing the label when you finish the beat).

I’ve replaced all of the buttons with black buttons, and replaced the pads with NOS pads, and all of the slider were replaced with new ones. The LEDs were replaced with white ones. The floppy drive works great and I will include 20 floppies to get you going. The other SP I had was a little noisy on the power supply, but this one is super quiet. The screen is bright, and the filter chips have also been replaced with NOS new old stock ssm2044 chips which cost me I think it was around $100 per chip. Includes a replacement set of NOS pads ($200 worth). The Jazzcat sample input monitor mod ($100) is installed and can be unplugged to disable. This allows you to monitor while sampling without reading a mixer. This one has smooth sliders and fat fader caps.

This machine was taken care of and you won’t find another package like this for sale. I’ve seen many go through websites, and there’s a lot of questionable issues that come up. They almost always need some sort of repair. For example the first one I got needed all of the buttons replaced, but the seller said it was in perfect condition. Luckily, I’ve been repairing vintage synths for years and could take care of the issues that came up. I always use Cardas quad eutectic silver solder on all of my vintage gear repairs and mods.”

“Firstly, please know that I am an amateur with synths. There are waaayy too many buttons and features for my acoustic guitar mind, so please understand that I am doing my best–and don’t take my explanation of what works as 100% true. No matter what, I am selling it as is, for parts or repair.

It took me a while but I figure out how to produce sound from the keys. All that I am able to tell you about the functionality is what you see in the video.

Every key works but the A sharp key on the right is sticky. Others possibly are sticky as well but they all seem to respond the same to me.

There are a few marks on the keys on the right (pictured).

The screen and its brightness seem normal to me.

I don’t like how the some of the buttons feel and a few are a little sticky as well.

The rotating selector works and the sliders seem to work, as well as the modulators.

There was a disk in the drive so I attempted to access the information on it but I was unsuccessful. I did hear the drive try and engage, but again, I have no idea what I’m doing…

No inputs were tested other than mono.

Has some scratches, scuffs, and overall signs of wear from playing gigs.”

“I am original owner, purchased 1984 when it first came out. I then purchased the SG05 upgraded module installed as shown (Original SFG01 module also IS INCLUDED! ) giving extra features and MIDI in capabilities, and eliminating the need for the YK series keyboards!

I used the included COMPOSER cartridge to create complex multitimbral songs, and some monster real time jams…then after a little over a year of light usage, I put it in storage.

I am moving soon, and cannot take a bunch of my vintage gear with me so I hope someone will enjoy this clean, very well preserved kit.

PLEASE NOTE ! INCLUDED is the original SFG01 Module (easily swapped with only one screw) as shown in the last picture (SFG01 module is not shown in Main Photo) : IT will give you an (upgradable) spare module.

This 4 operator module is capable of truly amazing FM sounds, in addition to being an early beast of Konami video games and graphics, (which I never used it for that) but there are still

incredible 3rd party patch data available to this day, if you dig a little..or, for the adventurous, program your own with INCLUDED Voice Editor.

I very carefully have had it in dry closet storage nearly 40 years now, in case I needed it again… I TESTED it via external MIDI keyboard, utilizing the “call_music” command. and it still functions perfectly playing the tones ( Japanese Yamaha 80’s build spells quality)

The original video RF video adapter is included, as well as the cassette tape interface cable, which I have not tested , but worked fine last time I used them (requires cassette deck and/or TV/ monitor capabilities)

I am not an MSX Basic programmer perse, but a valuable extra included is the MSX programming book I purchased as well… as shown.

At 1984 , I simply could not believe how cool this MUSIC COMPUTER was, and actually still is ! If you can write music, the included COMPOSER software, can take you in interesting directions as well.

In addition to tape backup, which was very reliable for me,and all I used, there were other backup drives available, which may still be obtainable, but I think other storage/load data methods may be more efficient…sysex mabe ? I think there are some utilities available for this function….at least there used to be !

Keep in mind, the SFGO5 can do up to 8 part mutitimbral, and combinations of that, and accepts MIDI in, unlike SFG01.

Manuals (4) show some minor wear, but are all intact, except FM Voicing Prrogram has back cover page missing (superfluous) , and COMPOSER manual has back cover missing and 1st two pages missing only. MSX book is in excellent condition .” Click here to visit listing on eBay

“Korg DW-8000 Programmable Digital Waveform Synthesizer w/ Case & PS-1 Pedal READ. The synth does work it does power on but it does have some issues.

“Korg Polysix PS-6, reluctant sale of my 1982 vintage analogue programmable Synthesizer. I’ve owned this synth from new, it’s never been gigged and only used in a home studio setting.

These synths are now very collectable, and are getting quiet rare on the UK retro market, only ones I can see currently on sale are in Japan or the US, some non working ones I’ve seen advertised for more than I originally paid back in 1982!

Please check online for full technical specs.

The synth is in great shape for its age, physically there are some small chips out of the wooden end cheeks ( I have seen a lot worse on eBay claiming to be mint)

There are also some fine scratches above the attenuator knob on the front panel and some on the letters K and O of the Korg logo on the rear panel, I have photographed them as best I could to show.

The mains input is now on a standard IEE socket with a supplied lead, it is UK 240v 3 pin.

The original Leakey Nicad battery has been replaced once in its lifetime, and a repair to the PCB done at the same time a number of years ago.

I have another new PCB battery which is included in the sale, but I’ve not got the ability to do the replacement myself.

All the pots and switches work ok, although the volume pot is a little crackly when not used for a while, contact cleaner would most probably sort

that out.

In the area of the volume pot there is the slightest dint in the metal front panel, it is hardly noticeable, and I’ve shown it as best I can in photo No9.

The keyboard contacts have been cleaned sometime ago, but when not regularly used a couple of keys become hesitant at first, but are fine after a bit of use, mainly top G.

There is an extra jack socket fitted to the rear panel, it’s not connected to anything.” Click here to visit listing on eBay

“The legendary one-and-only Arp Odyssey 2800 mkI “White Face”. Pristine completely restored original Arp Odyssey 2800 mki White Face duophonic analog synthesizer from the early 1970’s. A historical and fully functional piece to say the least.

Sounds incredible and functions perfectly. Much more fullness and more aggressive sonically than Moogs, black face models and many reissued Korg models.

Fully cleaned, serviced and keyboard reset by the fabulous Switched On synth shop in Austin, TX (original shop that Stranger Things composers Kyle Dixon & Michael Stein worked at).

I put $1200 into of perfecting this unit and then barely ever used it. Never gigged, has only sat in a nice temperature controlled studio.

This is probably the nicest original early 1970’s ARP Odyssey 2800 unit you’ll be able to find for sale in 2022. Only two owners, I bought from the original owner 15 years ago. It does have some cosmetic wear and tear, and dings in the paint from yesteryear, but no new cosmetic wear since I came into owning it, as it has not gigged with me.

Features:

— Transpose Up 2 Octaves / Down 2 Octaves

— Portamento w/port to switch on/off

— 2 VCO’s (Voltage Control Oscillators)

— Duophonic – Stack 2 Oscillators or break them out to 2 separate notes

— Excellent Voltage Control Filter w/Frequency and Resonance

— High Pass Filter

— AR and ASDR envelope

— Ringmod and Noise Generator

— Pitch bend knob

— LFO

— Sample/Hold”

– missing battery compartment cover
– paint damage around the power button
– cracked mod wheels
– generally unloved

“This Listing is For:

A Used Vintage 1984 CASIO CZ-1000 Digital Synthesizer Keyboard.

This keyboard was part of my recording studio gear. I don’t remember where I got it but I recorded a lot of soundtracks with it. As you see, it’s been around and played a lot. There is plenty of scratches, rubs, etc… It’s not in a great condition.

I own it since 1990, now it’s in my keyboard closet because I cannot play anymore. Does not come with the DC 9 Volt power supply but it play with batteries. I only tested for 10 minutes with a pair of studio headphone and the keyboard was playing. I did not test everything because there is a lot you can do with it. It may need repairs, servicing or cleaning.

I have tried several times to reset it and it works for a while the goes back to the DECODE ERROR status when no sound at all will come out.
