Discussion about the Korg PolySix synthesizer

Hi,

I just grabbed a Polysix from eBay. Sounds fabulous, although there is a pretty significant 
noise/interference problem. I opened it to find the blue battery sitting there. Battery 
leakage doesn't look too bad.

Can anyone suggest the closest place to Toronto to get the battery replaced?

Will this help the noise issue at all once done?

Thanks,

Perry
