Die Dreh- und Schieberegler scheinen noch zu funktionieren.
Einige Taster lassen sich nicht ausschalten.
Vier oder fünf Tasten geben keinen Ton wieder. Vielleicht kann das ja durch
Reinigung der entsprechenden Kontakte behoben werden.

Ich verkaufe das Gerät deshalb als defekt.

Dies ist ein Privatverkauf.

This synth was fully serviced by James Walker of Synth Repair Services in November 2011. (I can provide receipt for this work on request)

You will receive a fully functioning Korg Polysix with no leaking battery timebomb. James replaced the old battery with a safe modern equivalent.

Cosmetic condition is great apart from some small scratches near the memory buttons and some slight wear on the corners of the “wooden” side cheeks. These are visible in the photos.” Link

Sound:

Der Klang des Polysix klingt typisch analog und hat aber seinen eigenen Klangcharakter. Obwohl er nur einen Oszillator pro Stimme hat (plus zuschaltbaren Sub-Oszillator) klingt er richtig fett. Das 70/80er-Jahre-Feeling, was ihn auch so unvergleichlbar macht ist immer im Sound enthalten. Die weichen und schwebenden Poly-Sounds, sowie die String- und Brass-Sounds gibt er sehr gut wieder. Superspielfreude kommt auf, wenn man bei laufender Sequenz an den Knöpfen dreht und seine Phantasie (musikalische) freien Lauf zu lassen kann. ” Link

Unfortunately, it does not operate correctly.

Powers on, lights up, but only makes a squealing sound on occasion.

Pretty decent cosmetic condition. Battery did show some minor leakage which has been cleaned away with dry brush and contact cleaner.

All wires and components intact. All knobs and switches are intact. Keys are in good condition.” Link

Included with this synth is a factory PolySix MIDI retrofit kit but this synth DOES NOT HAVE MIDI INSTALLED. The kit was taken out because I could not find documentation on it to test it or replace the EPROMS. When I first opened up the synth, the EPROMS had wiggled their way out of their sockets and I presumed the kit to be dead or damaged, so I left the kit out of the restoration to avoid complications. There are several kits on the market right now that could probably do a better job than this kit anyway. Nevertheless, this kit is included in the sale. If you are planning on installing this kit, I suggest that you consider making some modifications to the power supply to handle the extra current that will be needed. Korg had a really sketchy power supply boosting work around that I reversed because it appeared to be bypassing some of the power supply filtering to accommodate the extra current needed for the kit.” Link

Update: this unit was listed before but the buyer backed out. Also, the battery has not been replaced and has leaked slightly onto board #367 as those of you familiar with this may ask.” Link

I am not an expert on this keyboard. Recently took this keyboard on trade.

Plugged it in and all of the keys work.

On the left as in picture3 all the knobs, modulation wheel, and bending wheel all work.

Some of the bottoms on the right as seen in picture 2 are not working. I am not sure if this needs to be reprogrammed.

The to tape, error/cancel, and loading/write buttons are always on.

Some of the program buttons work and some do not.

Keyboard has tape residue, scratches and wear.

Sold as is. ” Link

im absoluten Bestzustand, stand immer in meiner Wohnung, war Erstkäufer.

Der Polysix ist techn. und opt. im Bestzustand.

Dazu lege ich noch die original Bedienungsanleitung , Setting Charts, und eine Kasette mit Factory Charts.

Korg Polysix in very good condition with Manual, Setting Charts etc. The Polysix is like new, wasn,t out my home.” Link

This is a premium build, with every chip mounted in machined-pin sockets, all-new electrolytic capacitors, instead of ceramic capacitors poly or silver-mica caps are used instead, and multi-turn cermet trimpots. In every instance possible, the chips and other rare components from the original CPU were transferred to the new board. Assembling the board was labor-intensive. EVERY recycled part from the old board had to be tested (I mean, it just wouldn’t do to put any parts that were killed by the battery damage on the new board!), and the board has approximately 870 holes to fill with parts, and nearly that many pins had to be unsoldered from the original board. The third photo shows the process near the beginning, and the last photo shows the job complete. The board was then installed and calibrated to factory specs.

Installation: (If you are not comfortable with electronics, PLEASE get a qualified tech to install this) Back up your patch data, it will be lost during this process and need to be reloaded when done! You will need to unplug and remove the old board first (duh!). Be careful unplugging the cables, most of the connectors have been glued in at the factory, and the glue seal will need to be broken. Carefully unplug the processor chip from the original board, taking care to not bend any pins, and plug it into the new board. IMPORTANT: Do not forget to do this, the processor chip itself is the only piece you need from your original board, and is NOT included in this auction! Screw the new board into place. ALSO IMPORTANT: There will be a thick black ground wire going from the control panel to a ground point on the original board. This is the only wire that needs to be soldered, and it must be done. The grounding point is already prepared with solder to make this easy. Install the battery (included!), Plug all the cables into their correct sockets (nearly impossible to mess this up!), close the hood and play! There is no need to calibrate this board, it has already been done for you, and a different processor chip will not matter.” Link

- Keybed and contacts cleaned in spring 201, couple keys could use another clean for better keyresponse” Link

In ‘as-is’ condition. Comes with stand. ” Link

All kinds of lights come on when it is plugged in and turned on, but I have nothing to test its operation or output with, and wouldn’t know how to test it if I did…so I’m selling this AS IS, NOT WORKING (as far as I know) FOR PARTS OR REPAIR only, with no return. ” Link

Cosmetically there is a few minor blemishes, one key has a small chip that has been covered (pic 9), and a couple of chips on the wood, nothing really major, very clean overall.” Link

Er verfügt wie der Name schon sagt über sechsstimmige Polyphonie und die typischen Filter und Envelopes eines analogen Synthesizers.

Das Gerät wurde regelmäßig gewartet und befindet sich technisch und optisch in einem guten Zustand (siehe Bilder).

Vor zwei Monaten wurde die Originalbatterie samt Platine gewechselt. Ein typisches Polysix-Problem war nämlich, dass die Speicherbatterie gerne ausläuft und die Platine verätzt und dadurch zerstört.” Link

This example is in very good condition, with the exception of a couple wood corners–a typical cosmetic problem on Mono/Polys and Polysixes. It works 100% with no issues. The battery was replaced with a lithium coin-cell, to prevent the common Polysix battery leakage issue.” Link

Ich verkaufe meinen Korg Polysix mit schweren Herzens.

Der Synthesizer ist in einem guten Zustand und klingt weitaus besser als die VST Version.

Liebhaber und Kenner wissen, was hier für ein Synthesizer angeboten wird!

Die Manual ist im unteren Link zu finden.

Das Gerät kann auch gerne vorab in meinem Studio in Frankfurt am Main begutachtet und auch abgeholt werden.
Bitte schauen Sie sich auch meine weiteren Auktionen an.

Viel Spaß beim Bieten!” Link

have I used the inputs for VCF & arpeggiator. I’ve played this synth in its manual

mode and rarely ever stored patches. The current patches were saved by the previous owner.

Patch memory writing/saving functions are working but the battery for memory may need to be

replaced soon, as I’ve owned this synth for 2 & 1/2 years.

A new battery was installed by previous owner.

keybed is slightly loose in lower octave section. This does not affect playabilty.

Previous owner replaced brown wooden bottom and sides with black wood.

There are chips in the corners of the wooden sides. Red lights were replaced with blue. See photos.

Unison mode is functional but activity light is not working. ” Link

Gleich zu Beginn:
Das Besondere an diesem Polysix ist, dass er ein neues Prozessor-Board hat. Diese Platine wurde eigens dafür in den USA angefertigt und in professioneller Kleinstarbeit komplett bestückt. Sprich: Dieses Board hat noch nie einen sonst so üblichen Säureschaden gesehen und ist bis auf wenige Ausnahmen mit neuen Komponenten und einer Batterie ausgestattet – bereit, um ein Leben lang zu halten!
Des Weiteren wurde der Polysix komplett generalüberholt und sämtliche Kontakte wurden gereinigt, Tasten gesäubert, alles neu eingestellt, gestimmt usw.
Von daher ist der Preis ein wenig höher als üblich, der aber im Großen und Ganzen die Kosten und den Aufwand des neuen Boardes gerade deckt.

Es wird versichert, dass der Polysix 100%ig funktionstüchtig ist. Es gibt darüber hinaus eine 2-wöchige Reperaturgarantie, falls beim Transport irgendetwas Schaden erleiden sollte o.ä.!

Falls Sie bereits einen Polysix (mit Säureschäden o.ä.) besitzen und Interesse an einem solchen Prozessorboard besteht (auch inklusive Einbau oder Reparatur), kann ich Ihnen gerne weiterhelfen. Sie können mich jederzeit kontaktieren.” Link

many call this synth “the poor mans prophet 5.” ” Link

NOT WORKING HAS ISSUES…..

I made a restoration on this Synth about 3 years ago and had it completely working.

The battery notorious for leaking had corroded traces on the board (klm367). This was repaired by jumpering the
bad traces with tiny wires soldered to the underside of the board. The battery fix was done replacing the dead batt. with a coin cell type.
The bank and program switches were replaced. The keybed was removed and all the contacts cleaned. The factory patches were loaded and I enjoyed the machine.

Now it has returned to the land of the near dead.

None of the keys will trigger, may be the contacts are in need of another cleaning ?.
Several bank and program leds light up simultaneously, a sure sign of more problems with the klm 367 or switches.
This machine has received all the attention it is going to get from me aside from packing it up…

This unit is being sold PARTS OR REPAIR ONLY……. AS IS as is…..
Included is a bare non-populated replacement klm 367 board, and a cd with the user manual, service manual, and factory sounds ( copy of the cassette tape in wav format)

You will have to be very good with electronics to fix this machine. I would only buy this for parts, or if you were in the groove of other polysix owners who make it a hobby to re-build these machines. There is a polysix family on the internet that share in the klm 367 rebuilds.” Link
