“New internal battery installed. Rack ears can be removed for desktop applications. Correct factory power adaptor. Some scuffs from rack mounting, but overall in great shape. I do not have a data disk so I cannot test it, but I will accept returns, because I know where it came from, and have no reason to expect it not to work. One slider knob is missing, but the slider works fine and they are available cheap.” Click here to visit listing on eBay

” Selling my Kawai K4r rack synth.

The unit is in fully working order, some cosmetic marks and scuffs that you would expect from a unit of this age but nothing that affects its functioning. It still fits well into a rack as well.

I am including the original Kawai power supply. It is actually an EU plug but I’m including the UK adapter that I have attached to it so it’s ready to play as soon as it arrives!”

“This is for a Kawai K4R 16 Bit Digital Synthesizer Module in *Parts/Repair* Condition
Not POWERING ON…Nothing.. Not a click, not a flicker.. I could not get it to fire up with my universal/Multi-tip adapter… NO further testing performed.
I honestly think there is just a little corrosion at the POWER input or perhaps a FUSE that needs to be replaced?
The device looks to have never been opened up…
If you are good with vintage electronics this will most likely be a simple repair

NO Power supply or other pieces included.. Main device ONLY

Missing 1x SLIDER KONB…… Otherwise, VERY GOOD COSMETIC CONDITION…
No other flaws or issues to point out
NO rust, dust or oxidation
NO evidence of being dropped
NO burnt electronics smell
NO rattling or loose pieces”
