Korg Poly 61

“Up for auction is a Korg Poly-61 Vintage Polyphonic Synthesizer in non-functioning operating condition and nice cosmetic condition overall. I intended to restore this and started by replacing the leaking original internal battery. Unfortunately there was some damage done from the battery residue and some of the traces on the board will need to be repaired. I have taken a close up photo of the area near the new battery which shows the damaged traces. The other thing I did was replace all of the keyboard contacts with new LA Synth Co. contact strips. Because I own another Poly-61, I was able to swap out the keyboard to test it on my fully functional version. The keys all function perfectly with no issues.

As this unit stands now, it powers up and all lights function but the sound and behavior isn’t proper. The parameters don’t affect the tone the way they are supposed to and sounds will play when they aren’t supposed to and things of that nature. ” Click here to visit listing on eBay

“Korg Poly-61 synthesiser (1983), good condition, but some keys not working. Synthesiser was fully working when it was put into storage and has been left untouched for a number of years. Recently tested and approximately 10 of the keys are no longer working. Some of these faulty keys occasionally work, so suspect it is the contacts that need cleaning. Recommend a full service by a professional including replacing the internal battery. The pictures are recent and all the other elements of the synthesiser appear to be working as expected.” Click here to visit listing on eBay

“Unit powers on but has a short circuit on the board. When powered keys play without being pressed. You can get the keys to stop play by pressing down but then they start shortly after. Some do not play even when pushed down. Being sold as is for parts or repair, no returns.” Click here to visit listing on eBay

“Korg Poly 61 Keyboard Synthesizer. Condition is Used.
I’m no expert but unit turns ON and the display , all leds , and knobs work as they should. Joy stick works. Arpegaitor works…basically, Everything works as it should. Tested both 1/4″ headphone and output jacks. Sounds great!
Unfortunately,
One broken missing key and one key that needs to be put back in place (have 1 key and spring) actuators for these keys work so just a matter or replacing installing the keys. A few small dings and scratches but overall in good shape for its age. 1983?
Revised: The battery has never been replaced but i checked it and its not leaking at all. (See pics)
While i had it open i placed the key and spring back onto the keyboard.” Click here to visit listing on eBay

“This auction is for a KORG POLY-61M key synth vintage analog keyboard with MIDI “FOR PARTS”. I put it for parts because there is no sound coming out of it. The keyboard turns on. Every time you press a key it sounds like a tick. Every time you press a key the diodes on the board(508A) inside light up. I tried to find out what chip,diode,capacitor or resistors were bad but it was an impossible task for me because I don’t have the right equipment to test it. It seem like they spilled something on it. I took out the board(509A) and cleaned it out but to no avail. So I’m selling this AS-IS. From what I have been reading its a pretty simple fix. Please look at the pictures for more details and condition. Thanks and good luck.” Click here to visit listing on eBay

“Hello,
Up for auction is a Korg Poly 61 synthesizer from the early 80’s.
It is being sold as is.
When you turn it on, some of the button’s lights come on, but pressing the buttons doesn’t turn off the lights and the LED patch number doesn’t come on.
Also, no output.
It looks pretty clean though.
Hopefully someone out there can bring it back to life.
Good luck and happy bidding!” Click here to visit listing on eBay

“Vintage 1982 Korg Poly-61 Synthesizer – Partially Working For Parts/Repair Only. This powers on and the displays (Program no, Parameter, Value) change as they should when you press the buttons. I tested the sound with headphones but did not have an amp to hook up to it for testing. I got sound through the headphones when I pressed some of the keys, but not others. I’m not sure if that’s because of settings that needed changed or if an amp is required, because I know very little about these machines. It may work completely and correctly but I am not sure, so it is being sold as parts or repair ONLY. The joystick is present and straight. There is some slight damage to 2 of the corners as shown in the pics. Photos show the actual item you will receive. This includes ONLY the Poly-61, no additional items. Local pickup welcome. We will combine shipping when possible.” Click here to visit listing on eBay

“Korg Poly-61 Analog Synthesizer sold AS IS for parts or repair. This is partially working and powers up and has sound output (tested with headphones). Led display lights change as they should when buttons are pressed. The frequency and arpeggio speed knob lights flicker faster and slower when the knob is turned. Cosmetically it is in decent shape except the wood side panels are beat up. The other issues are only about half the keys produce sound. This could be because it needs a good internal cleaning or some other issue. Judging by the amount of exterior cleaning I did there is probably a lot of internal dust. The joystick is slightly bent but still functions as it should. And it is missing one of the rubber feet on the bottom. Due to its age and condition there may be other issues not yet found in my testing. This is a great project to refurbish or to part out. From a smoke free environment. ” Click here to visit listing on eBay

“This is a vintage Korg Poly-61 synthesizer. The Korg Poly-61 exhibits pinholes on a handful of the lower octave keys made by the previous owner. Not sure the intention or purpose of these holes but nonetheless, it is not affecting the playability or overall integrity of the keyboard. Also, each of the corners shows wear that is normal for a keyboard of this age. Overall, the Korg Poly-61 is in very good condition. The Korg Poly-61 is fully functional and operates as intended.” Click here to visit listing on eBay

” Selling my custom Korg poly-61 in great shape. Manual controls of cutoff, resonance, attack, decay and sustain have been added so you don’t have to menu dive for those common elements. I wired it so each potentiometer has a corresponding on\off switch for turning each parameter on or off. Midi in and thru have been added on channel 6. I proactively changed the battery to ensure there wouldn’t be any leakage or damage to the board. This year I cleaned and rebuilt the key bed. All knobs, buttons and functions work as they should. The synth sounds fantastic! The factory bank has been loaded in preparation for this sale.

Cosmetically it has some scratches and dings, particularly around the side panels. Those are pictured. When I had it apart last time I lost the screw for the DCO and Pitch bend panel so it stays put, but the panel has a bit of wiggle to it. It doesn’t impact performance but thought I should mention it.” Click here to visit listing on eBay

” Vintage KORG POLY 61 programmable analog polyphonic synthesizer. This one has had a rough life but its not totally dead yet. Many physical issues including missing & broken keys, missing joystick, broken switch, general wear, dirt, etc. Please check the photos. Just powered it up and its droning away on its own with no keys seeming to work, but I was able to use the PROGRAM and PARAMETER functions. When I’ve tried it in the past sometimes it does nothing, something a few keys work and the arpeggiator works, but it is 100% As-Is. Hate to throw it away so hopefully somebody out there can use it.” Click here to visit listing on eBay

“Picked up as part of job lot,

Facia /front panel clean with some surface scratching

Some damage to corners , bear in mind this was released in 1982 , it’s been around for.some time .

Some damage to lip of top.of front panel as can be seen in pictures

Other tha that reasonable/ok condition

Synth does turn on but no sound /clicking heard through headphones,

Have tried to find how to factory reset bit from what I’ve researched , I need a tape player so this would suit someone with a good working knowledge of analogue and synthesis factors

Think that’s it , have tried to be honest and open

It’s big and heavy so collection only ”

Korg Poly 61 Keyboard Synthesizer, 1983 – non-functional, Fair Condition. Condition is For parts or not working.
I have owned this Korg since 1996 and it’s always been kept in its heavy duty case. About 8 to 10 years ago, the voices stopped producing sounds when it was first turned on. At this time, it will sometimes produce some sounds after being powered on for over an hour. I believe there is a capacitor issue, or that the board needs to be tested and re-chipped. It cannot be actively used without maintenance work performed.
As such, I am listing this as Non-Functional and For Parts. Interested buyers would be those looking for a project or scavenging this one for parts.
The joystick in the picture was customized as the original broke some time ago. I still have the original joystick, as seen in photos, and it will be included. Perhaps someone with some 3D printing skills could replicate the original to fully gain use of both axis.
Note; the battery was removed to avoid it leaking and causing corrosion. I will update the photos with a close-up of this area. I do not believe that there is any corrosion, and I removed it as a precaution.
The case is overkill and extremely heavy and probably should not be shipped. The metal trim makes it a bit dangerous, and I think this was a custom tour case built in the early 1980’s. I will gladly ship without this extreme case and just use alternative padding provided by FedEx.
Any questions? Please do reach out! I want this synth to go to someone who will do something useful with it, as it’s a joy to play when it does work.
Shipped with FedEx Ground or FedEx Home Delivery. ” Click here to visit listing on eBay

Korg Poly 61M

“I replaced the side panel. Its not stock. All the original clips are put back, but some screws are not original. It plays really nice. Once you get used to the slider, its easy to use the value lever to program, and in performance on the filter , envelopes etc.
You have alot of performace control with the live buttons on the panel , chord memory, hold, 9 different arpegiator positions, either latched or unlatched, live speed control. the joystick is and XY postions so you can blend the pitch bend with the filter, or vibrato modulation. The pitchbend goes up to an oct up and down, and has a live knob control that amount, and another knob to control the frequency speed amount.
Tuning knob on the panel.
Pedal controls include, sustain, program up, arppegio trig in,
High and low main out, AND headphones out
This synth really is a monster, and it does some unique sounds when you push the edge of some of the controls, like good analog synths do.
It takes a minute for the osc to stablize, which is normal for the poly 61m till it warms up. But it tunes itself” Click here to visit listing on eBay

Electrolytic capacitors were replaced on CPU board and power supply board. However i do not have the time to finish this.
I get sounds out of it but they sound weird. I am not to familiar with synths, from My research i am guessing its a bad trace. It seems all the voltages are there. But again. Im not an expert.
Im sure someone knowledgeable can get it going easily. The joystick works.

“Korg Poly 61 Vintage Synthesizer.

This is a great sounding synth and easy to program.

There are a couple of issues;

1. The mode switch is broken but still usable

2. The top c has an intermittent fault.

Everything else works as it should. The inside is clean with no battery leakage.

The case is a little tatty, but doesn’t detract from the functionality, of the synth.”
