Korg Poly-61M

” Korg Poly-61M completely refurbished, new oak chassis, new switches, Beautiful !

This synth was in very good condition, even before I refurbed it. I just wanted to create the best possible P-61M I could. It has never had a battery leakage, although I have updated the battery to a modern 3.6V lithium coin battery (2032) with an easy access battery holder. I refurbished the keyboard, cleaning it thoroughly piece by piece, and after polishing all the contacts, I applied the little carbon discs to each contact, as seen at sounddoctorin.com. It’s a brilliant fix, so now the keys play like new. Then I replaced all the program buttons’ switches with brand new ones, which fixes the annoying problem of not getting the buttons to work properly. Now, they are perfect. See the photo of the switch board with new (blue) switches. Then I built a brand new solid oak chassis for the synth, so as you can see, it is gorgeous, and now more solid than new. It was finished with a Satin Ebony polyurethane that goes very well with the gray panel. All pots lubricated, new knobs, all bolts and inserts for the chassis are new, and new rubber feet. Nothing is missing.” Click here to visit listing on eBay

” This was Korg’s follow up to the now classic Polysix synthesizer and it if very similar. I just do not have time for anymore repairs / projects. It could possibly be an easy fix for someone that works on these. Notes are being held for some reason. Not sure of the battery works or not but I think it is a working replacement. It seems like everything else is working and it sure sounds great. Check out the little demo video.” Click here to visit listing on eBay

“Korg Poly-61, had the leaky battery problem. Battery board is pretty rotten. Has been cleaned up some, but still not working very well. Powers on and can play some strange sounding patches. Doesn’t let you edit the patches, doesn’t let you transfer in new ones from tape. Joystick is partially working. Very scratchy volume knob. Sold as is, no returns.” Click here to visit listing on eBay

“KORG POLY 61 Synthesizer Vintage analog. Needs care. Powers up but sound output is erratic. keys may be dirty. I don’t know.
Cosmetically in good shape. I think it could be brought back to life.

So. the sound output is erratic. In some patches you press a key and sound comes out, some you have to hit hard to make a sound. Some patches, when you hit a key the note holds. some keys and patches don’t produce a sound at all.”

“Works good. Some damage to bottom edges. Joystick is bent. Number 1 button sometimes re-triggers. See pictures.

This was Korg’s answer to the Roland Juno-60 and it looks like a Juno-106 but the Poly-61 is more interesting in many ways.” Click here to visit listing on eBay

“Excellent vintage condition as shown in the photos. Hard case shown in the photos is included in the auction. It has scuffs and some oxidation on the metal corners and latches. There are no dents or damage on the keyboard itself that I can see. I am listing it with the condition as “for parts or not working,” because I have no facility to test it. It belonged to my late father who was a professional musician. I obviously can’t ask him about it now. So, AS-IS, FINAL SALE, no refunds or returns on this item.” Click here to visit listing on eBay

“KORG Poly-61 Analog Synthesizer – poly 61 korg. Condition is “For parts or not working”. Collection in person only.

I brought this refurbished from eBay around 10-15 years ago. I believe it has had a new battery installed (I cant see any signs of damage on the motherboard) as well an additional memory bank – this can be toggled on and off using a switch (See pictures)

It works intermittently, times when it doesn’t work the volume is very low – sometimes it has to warm up. Not all keys work – maybe 10 of the 61 are dodgy (theres a delay) and the pots are noisy. The case shows wear and tear, especially on the feet and the back. The digital display and the number selector doesn’t work correctly – sometimes different numbers show – i.e. a 7 for a 1. Sometimes, pressing a parameter button will trigger a note – quite odd – sometimes a weird high pitched buzzing sound is played alongside a note. Defiantly a project for a someone who knows what they are doing and TBH I don’t have the time or patient to mess around with it. ” Click here to visit listing on eBay

” Korg Poly 61 Refurbished and with a New Solid Oak Chassis, New Main PCB, Excellent Sound. Condition is “Seller refurbished”.

This is a special fully refurbished P-61 with some great improvements, in top condition, and it sounds and looks fabulous. As you know, the P-61 is a great-sounding analog synth, with a real analog audio signal path, but with the advantage of digitally controlled tuning. As a result, this synth has that great classic sound, and the tuning is very stable. This particular synth has been refurbished with these features of note:

– The main CPU board (KLM 509A) has been replaced with a brand new replica from Andrej Shenshyn of synthronics.de in Germany. (That cost me over $300 US – see the photo).
– I refurbished the keyboard, cleaning all the keys and contacts, and solving the issue of faulty contacts by putting conductive carbon discs on all the contacts, per the solution by Sounddoctorin.com (a great solution to faulty key contacts – look it up). I added the extra effort to glue thin plastic pieces to each of the keys’ hammer stem, to make the contacts activate even better. Now it plays with a nice light touch, with no dead keys.
– I removed all the tactile programing switches, and replaced them from a large pool of 68 used switches that I had, testing very carefully and selecting the best-working 17 switches to use. Now the program selection buttons work perfectly. Gone is the frustrating issue of hitting the buttons a bunch of times to finally select the program you want.
– I cleaned all the pots and switches with a spray lubricant, so they are all working fine with no scratching noise or jumping values.
– The KLM 508 voice board has been fully calibrated, and it is in good shape. I replaced one interconnect that was faulty, so now it is fine.
– I built a new solid oak chassis for this synth, because as you probably know, the original was made of cheap particle board that was one of the main complaints of the P-61. This is a beautiful replacement, built very solid and the panel and other parts fit perfectly, giving this synth a better-than-new look, and it will be way more durable than the original. I gave it an ebony stain, to go well with the gray panel, with a satin polyurethane finish for a classy soft look. ” Click here to visit listing on eBay

“Synth powers on and does produce sound. However, the sounds seem to be random and erratic, and no longer correspond with the programs on a consistent basis. Also, it appears some of the keys may be sticking – not physically, but certain presets will produce sound even when no key is being pressed.

Synth was in perfect working order until I recently moved across the country and plugged it back in. My guess is that something internally must have knocked loose during transport. I did briefly open the panel just to see if there were any obvious issues such as an unsoldered wire, but nothing stuck out to me. Cosmetically, the synth looks great, with only some light chipping in the paint on one of the side panels (see photo). All buttons, keys and joystick work.

This would make for a great project synth for anyone interested in tinkering around with it.

I’m selling this synth “as is”. I described the problems as accurately as I could, so please make sure you’ve read my description fully so that you know exactly what you’re getting before purchasing it.”

Korg Poly-61M

“Up for sale is this fantastically cool Korg Poly-61M which I purchased new an eon ago in the 80’s! It is now looking for a new home. There is the usual wear on the ends. All keys function properly, volume and other knobs work fine. I’ve used this keyboard infrequently over the years and so the key action is close to new. Rheostats toggles and switches work fine. Button pads 1-8 also work fine but sometimes one will double tap instead of single tap. This is likely oxidation on the contacts due to infrequent use of the instrument, it “should” correct itself with increased use or cleaning. This is a bulky (but not heavy) item, pickup only. Fantastic vintage synth sound and feel can be YOURS!!” Click here to visit listing on eBay
