Korg Poly 800 Project Machine

“This is my beloved Korg Poly 800 – I bought it when it came out and it’s been with me since.

As a synth it works perfectly well, the only problem is that as I left the batteries in for too long they oxidised, and as a result part of the battery bay and part that connects from there to the circuit board has been eroded a bit by that. As a result of this and the internal battery also being depleted, the machine currently won’t hold settings/presets after being switched off.

I have tried to fix that, and in doing that I did manage to have it on just with the batteries (as you can see from one of the main picture in this listed, where it’s on while not connected to the mains) – but the fix I did was a bit flimsy and didn’t last long. I am sure that some capable hands can sort this out very easily – I am just not that technically/manually minded so not the best person to do that kind of soldering etc.

I uploaded the full set of presets using a soundfile that mimics the original Korg tape and while a bit hit and miss, it did work a couple of times, so that function also seems to work fine – it just won’t hold them unless it’s left on, or the battery thing is fixed.

I also developed a sound just to check that the various parameters work OK and they did – see the video included in the listing (apologies, as I had no time to hook it up to an amp the sound in the video comes from the headphones).

Other niggles:

– the top of the wheel is missing
– the chassis has a few marks here and there – see pictures
– a key is not working – circled in red in one of the pictures
– the bottom side of a key is slightly chipped – see pictures

Otherwise tin relatively good state considering its age – now just waiting for its next, second owner who will take care of it and bring it back to full functionality after it’s been with me for a large part of my life.” Click here to visit listing on eBay

“Very Rare Korg Poly 800 mk.1 Reverse Keys Version with a handmade wooden case.

Well looked after example, plays and sounds great. I couple of bits of slight discolouration on the plastic which is unsurprising on these.

I’ve had this one modded to have an internal battery fitted meaning there’s no need to use batteries for patch memory.

The wooden flight case has seen slightly better days but has done a super job of keeping this guy safe and sound.” Click here to visit listing on eBay

Korg Poly 800

“Here’s my Korg poly 800 synth for sale. Had it more than 30 years, still works a treat. It’s mostly un-modded…..the only change I have made is to add a holder for the internal battery (that maintains the flash memory). For some reason when they were built this battery was soldered in…. very odd! Battery was replaced a couple of years ago.

The synth is mains powered….the original adapter is included….but can also be powered by 6 D type batteries if you need mobility.

Everything is in working order….the on/off/volume knob is a bit scratchy but there’s no dropping out. The joystick for pitch bend and modulation works fine, as do the midi in/out sockets and the tape in socket. I had to reset all the patches to their factory settings when I replaced the internal battery.” Click here to visit listing on eBay

“Barely used since I bought it about 10 years ago.

Patches are saving onto internal memory but no factory patches remain. No idea when or if the internal memory battery was replaced. Remember using the midi back in the day so pretty sure that works but haven’t tested the tape ports but nothing to suggest they don’t work.

End key is very slightly skewed but still works fine.

Seems to be a few screws missing from the back plate but its solid and you wouldn’t know without looking.

Recently bought power cord included.” Click here to visit listing on eBay

“Vintage 1983 Korg Poly-800. Powers up and makes Synthy sounds but it’s like something is stuck. Change program number and parameters and the sound changes slightly but won’t normalize. Joystick functions and seems to effect the note properly. Anyway, sold for repair or parts. There’s an internal watch battery soldered to the board that eventually dies and required replacing. At that time a reload of original presets is also required and can easily be found and executed with 1/8” audio from the internet.”
