If your Poly has one, MK1 normally doesn´t have a battery (but you can solder one inside)....seems to be a general problem of KORG-Syths, which were built in the 80s. Polysix, Poly61, Poly800, some DW/EX...they seem to have all this battery leakage problem....

indeed
especially poly61

I had three Polysix and all of them had this battery leakage problem. As long the solder tacks of the 74LS08 are affected, it is no big problem to repair. But if the conductive strips and the RAM/ADC below are also attacked, -then- you´ll have a problem.....the Polysix mainbaord is really obsolete, but i am working on a replacement part. Oldcrows sells one, but he is located afaik in the US and the board costs afair 150$ without shipment. For me simply too expensive.
But in first order i have to repair the JP8000. Enough work for 1/2 days.
