"If your looking at this then you know what it is and how amazing of a piece it is. It is a monster and sounds absolutely huge. The PSU and entire keyboard has been recapped and serviced. All voice cards have had caps replaced and bad trim pots replaced. The keybed bushing have been replaced and adjusted. I just had the entire keyboard calibrated and overhauled by a very experience Tech name Bryan . Everything works and holds tuning but I can not guarantee a minor tweaker will not be require after shipping."

"Sliders have been replaced. Key bushings have been replaced. New slider caps have been installed and it has been serviced and functions very well. Few scratches here and there and the wood sides have dulled over the years."

I believe sides on the MKIII were actually a pressed leather. Curious what they are on this one and if wood, whether they are original. Did the MKIII come with wood side panels at any point?

"Not sure you can get a better PolySix than this.

KiwiTechnics 'KiwiSix' CPU Upgrade
KiwiTechnics brand new PSU
Custom power socket and midi connection panel.
Custom handcrafted solid oak case

The solid oak case is brand new, as is the cpu and psu upgrade. Aside from carrying out the upgrades I have fully serviced and calibrated the beast and she is ready to rock.

The KiwiSix CPU mod takes this synth into another dimension, it adds many, many new functions but most importantly gives the PolySix MIDI, and full MIDI CC implementation for complete external control, 4096 steps to each control also.."
