” Hello. I am offering for sale a 1983 Kawai SX-210 Synthesizer with Original Case. This really is STUNNINGLY BEAUTIFUL. My dear father purchased this for me when I was a child back in 1983 along with the protective carrying case. I didn’t use this very often and it has been lovingly stored in my parents house for 37 years and going. A nice opportunity to get a Kawai vintage synth is excellent condition. And rarely does the original protective carrying case make it this long too. Also included is the original manual, warranty and cool letter about the possibility of the synthesizer interfering with radio signals. How cool.” Click here to visit listing on eBay

“Kawai SX-210 Analog Polyphonic Synthesizer Near Mint. I performed basic testing and the synth appears to be in working condition. There is no battery leak and battery’s voltage is at 2.7 volts. If needed, I can provide wav files with factory default patches to load, along with a digital copy of the manual. The synth is sold AS IS. It will be securely packed prior to shipping.” Click here to visit listing on eBay

“No RAM battery – the synth will not boot up into the normal playing mode and does not make any sound, but I can still access the maintenance/adjustment features by playing the lowest C Major chord while turning it on, so it seems to still be alive. The panel test is is actually running in the first photo – that’s why all the lights are on.In addition, I did notice some corrosion on the circuit board around the battery, but it never seemed to impact the functionality before I removed that battery. Please see the pictures for the extent of the corrosion. Because of the missing battery and corrosion, I’m selling this for repair/parts despite that fact it was working fine with a battery.Cosmetically, the “BANK D” button is missing its plastic cap, and a G key is chipped and cracked. These still seem to work though. Typical scuffs” Click here to visit listing on eBay

“The Kawai SX-210 is a very rare synth. It’s an 8 voice poly synth with 4 poly stack mode as well as mono mode and chord mode. Built in chorus gives you the ability to hit those Juno sounds as well as polysix/MonoPoly sounds. It’s got Sub Osc, PWM, LFO routing/trigger and more. It’s a very capable and great sounding synth. It has a very large patch name display which is unique as it lets you write words for patch names rather than just a 2 or 3 digit number.

This is probably the best condition you’ll ever find one of these in.

Issues: The only physical flaw is on the wood side panel on the front tip there’s a crack besides normal wear. This doesn’t effect the functionality at all and could easily be replaced with new sides. The synth itself is great condition. Prior to shipping I will send a video showing functionality and you will give the OK before shipment. The Ensemble (chorus) button when enabled can cause some gain boost.” Click here to visit listing on eBay

“Condition:

This is a used unit.

Cosmetically in very good condition for its age. Only some minor wear and tear, mostly on the wooden sides. (Please see all photos)

Has recently come from a full service and calibration.

Brand new lithium cell battery has been installed. This has been mounted away from CPU board to prevent any chance of future damage.

Factory patches have been installed for the new owner.

Has been tested and this synthesiser is working and sounding as it should.

” Unit works with all 8 voices. However, banks A and B seem to have different issues. I do not know the problem but they are intermittent when selecting patches. Banks C and D look to function Ok as far as I can tell. It looks like all of the parameter functions also operate. I do not know anything about this unit as far as repairing it. It is being sold as I purchased it. I used it for Bank D which has strings and brass selections. It has a fantastic sound. It is being sold “AS IS”!” Click here to visit listing on eBay

“Rare Kawai SX-210 Synthesizer Excellent Condition Not working with repair kit

This a very rare Kawai SX-210 Synthesizer from a studio sale

All the keys and buttons feel right and the overall appearance of the unit is in excellent condition.

Typical battery leakage failure on main board. See picture, tracings have been tested with ohmeter and are conductive

Old battery has been removed and the last custom CPU repair kit from Portugal is included with it.

I have no time to fix this myself. All nearby components including rare CPU are included in the kit along with instructions for tech repair

No other way to test this so it is sold as is for parts or repair” Click here to visit listing on eBay

sx210 “I found this rare and excellent condition Vintage Kawai SX-210 Polysonic Synthesizer\analog keyboard at a local estate sale. This keyboard has been tested and works and sounds great! Very low start price on this professional full size analog keyboard. These were produced in the early 1980s by Kasai and are exceedingly hard to find. True analog sound from this vintage full sized Kawai soundboard. This was found at the estate of a local musician and has been very well cared for. This 61 key poly sonic synthesizer shows a little wear to the woodgrain sides as shown in pictures but is otherwise clean a works perfectly, producing clean a clear true analog sound. See all pictures. All original keys buttons and dials. Previous owner stated that he has never had any issues with this keyboard and was the original owner. These keyboard are very rare and very desirable to musicians as they are no longer produced This keyboard weighs about 28 pounds and I am extimating the shipping weight to be 30-31 lbs. All functions tested and working as designed and intended. No excessive slack or play in modulation wheel or pitch/bend bar. The only wear noticed upon inspection is a slight canting of the 32nd and 58th keys. Might be an easy fix at a music shop but keys work fine, they just hit the keys next to them (left and right respectively. No other issues but some cosmetic wear as to be expected for a 35 year old vintage price. All original down to the cord. This full sized keyboard measures 34 3/4″ inches long and is 6″ tall with knobs. Case measured 15 3/4″ deep from back to front. Very clean example that was well cared for and properly stored by the previous owner.” Click here to visit listing on eBay

Kawai SX-210 “Rare analog poly synth manufactured in 1983. No midi because this keyboard came out right before midi was available. Great sounding DCOs, very versatile synth with sub oscillator, poly 8, poly 4, or mono. All functions work EXCEPT some of the preset buttons.

Some issues:
I repaired the rotary controller which now works perfectly.
Some preset buttons don’t work or make an odd noise when pushed.
Output is noisy, but usually not noticeable when notes are played.
I will gladly provide audio demos upon request.” Click here to visit listing on eBay

kawai sx-210 “Up for sale is a very rare 6-voice Kawai SX-210 Analog Synthesizer. Functionally and Cosmetically perfect!! Internal battery was replaced years ago and has been regularly maintained. No battery leakage has ever occurred. These don’t come up for sale often, let alone in this type of condition. These keep getting rarer and rarer, because people neglect to fix the battery. As far as editing sounds on the SX210 Ive always found it much easier then on the SX240. Hit a button, then change its parameter with the main data knob. Very fun to program and also has it’s own very unique sound. Awesome for analog strings, pads, and even organs and basses. Truly an underrated classic. ” Click here to visit listing on eBay
