“It powers up.. the keys work intermittently.. it does make sounds.. the sounds loop when playing .. it could be the usual battery leak on the board but this one had a newer disc type battery so Iām not sure.. Iām sad to say good bye to it but this repair is beyond my expertise. The keys are a bit scratched and dull looking and the last key is crooked but still functions.. the case is in pretty good shape for its age.” Click here to search for synths on eBay

“Korg 01/W 61 Key Synthesizer
” korg poly 800 mk2 digital/analogue synthesizer. This synthesizer sounds fantastic. It has 2 DCOs and a noise generator each with their own ADSR envelope generator and most importantly it has an analogue VCF filter which makes this instrument sound great. It also has onboard digital delay, basic step sequencer and a MIDI interface so that you can sync it it sequencers, drum machines and computers with midi compatibility. Everything works on this unit except for 2nd D# key for some reason. The D# note still sounds if you play it from another controller keyboard or a sequencer or using the pitch bend but the actual key doesnt work when you press it. All other switches, sliders, knobs and keys work. It is 8note polyphonic. It comes with a real manual that you can actually read and it still has the original data tape cassette with it for factory sounds, though I have never used the tape and can’t verify if the cassette works or not. It still has the original box. I have not got a power adaptor for it but it uses the standard guitar stomp box 9V type. The original korg one broke many years ago and I just use my guitar stomp box adaptor with it now. This was the first synth I ever bought back in the 80s when I got my first job. I sampled it to death! Sorry to see it go. ”

” 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.”

“Korg Poly-61 Analogue- synthesizer. Needs repair- or for parts. Sometimes makes sounds when you press program buttons then keyboard. Loops the sounds. I think the common battery corrosion issue damaged the main board. A technician cleaned the board up but it still needs the leads to the main chip rebuilt and a few resistors replaced. Otherwise in pretty good shape.”
