“230V, no MIDI. Some dents on the wooden sides, minor scratches on the front panel. I tried to spot all of them. They’re not very visible. It looks very nice, works flawlessly and sounds beautiful. Overhauled last year, no battery issue, no scratchy pots, no sticky keys. I kept it in a soft case which I’ll give away with it.” Link

korgpolysix ” The iconic Korg PolySix Synth is for sale. Each of the 6 voices have designed VCO and sub oscillators creating a warm sound, softer and brassy-er sounding than the Juno. Specs include 32 programme storage allowing for recall of user made settings. You can select Saw, Square, Pulse Width and Modulated Pulse Width oscillators. Other features include an arpeggiator with octave, latch and up/down controls and a selection of effects; chorus, phaser and ensemble. This PolySix also has a modded midi input (running on channel 11), allowing it to be controlled by a daw or midi workstation. The PolySix comes with a case and the power cable comes attached. ”

“Classic Analog Keyboard (pre-midi). All keys work, sounds nice. But here’s an important issue. You cannot access or save presets. The keyboard works fine in “manual mode” only, which means you can dial in your sound, changing parameters, but you cannot save the sound/patch. Perhaps there is an easy fix, perhaps not. I am just not sure. Other features seem fine to me. The arpeggiator works, the fx section works (and the chorus and ensemble effects are terrific), pitch bend and modulation work. No dead keys. So, the keyboard is being sold as-is. Maybe you want it for parts, maybe for recording, maybe for nostalgia.” Link

“My Korg PolySix for sale. Built in 1981 it’s older than me. This sounds great, maybe a little scratchy somtimes on the headphone jack but everything works. It has some encap wood damage but nothing that compromizes the structural integrity of the synth. Has some spots on the metal panel that pave paint chipping off and superficial rust that can be cleaned off. There is a button missing the plastic but the button still is pushable and works. Please watch the video I made showing the synth and the blemishes. The synth is priced accordingly to it’s condition. The Red pieces on the keys are pieces of foam tape used to help me remember keys for a song I wrote. It just needs to be taken off” Link

“one of my favorite synthesizers…super warm, fun sounding synthesizer .

all the knobs and buttons work and the factory sounds are all reset on it.

There are about 12 or so keys that need to be warmed up, which is simply playing or pushing on them until are up to speed again…takes a few minutes if its not been used for a long stretch. If you don’t warm them up they react really slow, but once you tap on them for a few minutes they work like normal. this is new behavior after having it in storage for a bit. its likely an easy fix, usually just cleaning the contacts or worse case scenario replacing the rubber strips, all in all like a half hour pretty easy job. everything else works fine, and if you use midi, the voices work fine without warming them up. ” Link

Korg, Polysix @ 02 December 2017, Comments Off on Korg Polysix with MIDI

” Korg Polysix keyboard with Kiwisix midi upgrade and power bundle installed by LA Synth Co., which provides midi input/outputs, improved power supply, expanded patch memory, etc. I had it fully serviced and inspected by LA Synth Co. a few weeks ago – key contacts cleaned, pots inspected, etc. Everything works.

For the synth nerds – this Polysix was not a victim of the exploding ni-cad batteries that were factory-installed on these keyboards. The original KLM-367 circuit board that housed these batteries was replaced as part of the Kiwisix power upgrade so there’s no concern about battery acid corroding the circuit board.

If you purchase this synth, I will also ship you the original circuit board and parts replaced with the Kiwisix upgrade just so you have them.

Keyboard has some minor cosmetic wear as seen in the photos but nothing exceptional for a 40 year old synth. The mount that houses the mod and pitch wheel to the left of the keys is a bit loose (see last 2 photos) but has no impact on function or playing. Can be fixed with a few screws if it bugs you but it never bothered me.

It’s been a great synth to own but I decided to sell it because I never play it anymore.” Link

“This auction is for one Korg Polysix vintage synthesizer. It is in great shape with just minor dings on the sides. The dreaded battery problem is non-existent here as this Polysix features a brand-new CPU board (+battery). All voices work, effects work, etc. 2-3 keys need a harder press sometimes but that seems to come with the territory with these old rubber-dome keys. This synth sounds phenomenal and huge; a true classic!” Link

“Great Korg Polysix that has undergone major restoration. It has a brand new main board (not refurb, new), so no need to worry about the battery leak issue at all. Its been fully cleaned including key bed strip down and re build. The case has few marks and the end cheeks are very good for their age.

The power supply has been converted to 230v with a new toroid transformer. Midi in has been added. Its been fully tuned and is fully working and ready to go.

Classic synth in really great condition. Doubt you could find better.” Link

“Here is a Beautiful Vintage Original 1982 Korg Polysix PS-6 Keio Analog Synthesizer Project (for parts or repair) w/ Tapes & Manuals. S/N 388175. This plays and sounds ok but has some super glitchy issues associated with the battery leakage problems that these suffer from. This has had the battery leakage problem and someone attempted to repair the traces. I would suggest a professional repair it, or get a new $400 replacement circuit board available on the net. Cosmetically it looks great as shown. It looks to be complete and original. It comes with the original manuals, color brochure catalog Vol. 1 and three C-7 Patch Tapes. This will make a wonderful addition to anyone’s collection. ” Link

“Physically, the endcaps are pretty banged up as pictured, there are some minor scuffs, scratches etc, and a button cover missing. Not too bad though. Could be restored pretty easily. Functionally, it definetly doesn’t work right. I’m not sure what all is wrong with it. To be completely honest, I didn’t expect it to power up or work at all. I was able to get sound out of it however and what it did sounded good. Definetly not working properly though, being sold as is for parts or repair” Link

“Korg PolySix from back in the 80s in excellent condition with padded carry case.

Fully functional with no scratchy pots.

Korg PolySix six-voice analog polyphony with one VCO and sub-oscillator per voice. filters include chorus, phase, and ensemble effects. Excellent resonant filter with sawtooth PW + PWM oscillators. Can also be played in Unison mode with all 6 oscillators as a super thick mono-synth .

With 32-patch memory and arpeggiator controllable with 1,2 or all octave, latch, and up/down controls.

Tape back up to store more patches. Unit ships with ‘backup recovery tape’ to restore the synth to original preset patches.

Really clean, solid unit, comes with protective padded carry case, back up tape and cable.

Unit has a new battery from previous owner so memory works perfectly with no damage to the circuit board.” Link

Korg, Polysix @ 15 July 2017, Comments Off on Korg Polysix

“All pots work well, the programmer works perfectly/saves and recalls patches, circuit board cleaned, internal battery replaced/upgraded and has a midi-in retrofit. A real classic analogue synth and rare to be in this good-a-working condition; the unison mode is huge, the Arp is awesome and because of the Midi retrofit it can be sequenced via a DAW. Kept in a smoke free music studio and cared for like a person. I’m gutted that I’m having to sell this, but I’m having to raise funds.” Link

“Korg PolySix Analogue synthesizer in desperate need of servicing and some pampering. Think it has the common battery leak problem that seems to plague the PolySix. Can’t say if there is anything else wrong as it doesn’t work. Not too great cosmetically also and would definitely be described as in poor condition. Looks a bit of a project so sold as parts/not working.” Link

“The rare Korg Polysix. I’m clearing out my synths that need attention. This one has some banged up endcaps, some minor scuffs scratches, as pictured, but it’s not too bad. Could certainly be restored. Functionally, I honestly didn’t think it would power up or make sound, but I was surprised that when I turned it on it did made sound. It has a really nice voice. It definetly doesn’t work properly though, and is being sold as is non-functional for parts or repair only. No returns. Good luck to you, and have a great day!” Link

Good working condition with CHK midi upgrade. A few light scratches and a few dings in the wood (particle board) See pics for overall condition. The midi upgrade has repurposed the to tape socket so the case didn’t have to be drilled. Special midi cable will be included.”

“Not sure you can get a better PolySix than this.

KiwiTechnics ‘KiwiSix’ CPU Upgrade
KiwiTechnics brand new PSU
Custom power socket and midi connection panel.
Custom handcrafted solid oak case

The solid oak case is brand new, as is the cpu and psu upgrade. Aside from carrying out the upgrades I have fully serviced and calibrated the beast and she is ready to rock.

The KiwiSix CPU mod takes this synth into another dimension, it adds many, many new functions but most importantly gives the PolySix MIDI, and full MIDI CC implementation for complete external control, 4096 steps to each control also.. ” Link

p6 “Object of the offer

1x Korg Polysix synthesizer in great optical and technical condition
Serial number: 389050

Wooden case

The case is new
The wood is oak, it is treated by wax/gloss paint

Metal panel, metal parts and keyboard metal plate

New paint (powder coated) and new silkscreen
There are some small scratches on the new paint
Silkscreen inscriptions have some defects: “Intensity”, “Program”, “Programmer”. Check the photos
Almost all metal parts are powder coated to prevent the corrosion
Keyboard metal plate is completely powder coated to prevent the corrosion

Hardware, functionality

The hardware is very clean, there is no dust or dirt on the PCBs
KLM-367A and KLM-370 are new. The old PCBs were replaced because they were corroded. New PCBs ensure greater mechanical stability and electrical contacts. The functions are equivalent to the original boards
The synthesizer is naturally fully working, there are no electrical defects in this unit. So Arpeggiator, Filters, LFO and so on work very well
The whole unit was calibrated. The unit was triple tuned and stays stable and tuned. As well as possible for a Polysix synthesizer
Programmer is fully working and comes with factory sounds
All connectors ale clean and there is no corrosion
Some potentiometers were fully cleaned and treated by potentiometer lubricant to avoid sound “scratching” (e.g. Volume, Cutoff, Reso, Intensity, Tracking)
Keyboard rubber contacts were refreshed, so the keyboard responses great
Tactile switches are new” Link

p6 “Here today we have a Korg Polysix

The unit powers up but there is no response from the programmer circuits so the synth has no audio output or control of any kind. This unit was opened up and it has the dreaded battery leakage, (See Photos) so will require much TLC to get the programmer board working again. The rest of the synths condition is unknown but all SSM chips are there as well as all other components.” Link

6 “In working condition. All switches, LEDs,knobs and buttons work. No missing part or components. Have small dings on the wood panels, they are not major. Arpegiator and filters work perfectly. 6-voices are all working.

I can hear scratch sound while playing some patches but this is NOT the present on the others. Sound is similar to a dirty potentiometer. Not sure if this is a defect or not. Selling at a very cheap price so that you still have budget should this need repair but if this doesn’t need repair then this is a real steal deal for you. Unit is 110V.

Comes with Korg flight case as you can see in the photos. ” Link

korgpolyxi “The good:

Keyboard has been recapped, new wiring, battery replaced/modded, tuned/calibrated, includes complete Tubbutec Mody/Poly kit which adds midi among other features to this classic synth. The kit cost €179 + ship. So basically $200. Nice thing is you don’t have to wait on shipping or stock availability.

The bad:

The Arp suddenly stopped working. Everything else works perfect. It was working fine, attempted to send a CV via a Sub-37 to the Arp clock input, after that, it stopped working. The arp button works (engages arp mode), hold works in arp mode, keys work in arp mode, LED correctly follows arp speed via rate knob, but pattern does not arp. It’s almost like the clock input is still looking for a cv signal. I imagine this is a relatively easy fix. I have adjusted my price to reflect this. Aside from that and a few cosmetic blemishes (chipped wood, see pics), all is excellent.” Link
