Archive of the former Yahoo!Groups mailing list: Discussion about the Korg PolySix synthesizer

Hi,

I purchsed a polysix several months ago. Its the old production version with KLM-366 and the additional KLM-396a board on top of it. The battery had leaked but the previous owner repaired the traces and replaced the battery with a lithium with an easily swappable battery holder. Several of the keys are sticky and a couple are semi-dead (I kind of have to wiggle them sideways in order to get them to sound) and several are clicky (low felt probably). The top assembly is in great condition. There was a mod done to it that bypasses the effects unit (an additional out at full volume coming from the TPI sig out on the KLM-366 board with an in-line fuse).

I just picked up another polysix -- my plan was to grab the good componenets off of the newer one to mint up my older one. The newer poly six is the newer production version with the KLM-366s (no KLM-396a board on top of it). The battery was replaced in time; however, the new battery is soldered on and not as easily replaceable. The top assembly is in worse condition (pretty banged up and a couple rust patches, thick felt-tip ink markings on tune pot); however, the keys are in much better shape than my old one. There are a couple of semi-dead keys on this newer one as well (albeit different keys).

Which should I keep? The newer produciton model or the older one. Sonically they are exactly the same. The newer one is closer in key -- the older one needs to be flatted at the 9 o'clock position of the master tune to bring it into key. I'm leaning to wards replacing the top assemply with all the pots from the older nicer condition one into the newer model and then just replacing the couple of semi-dead keys (could be contacts though). Is there any issues with the top assemblys from the different production runs aside from that extra out mod that was done on my older model?

I plan on getting a midi-retrofit for the one I decide to keep.
