Korg DW8000, Mono/Poly, MS-20...

I picked up the most beautiful and flawless korg poly-61 today off
this guy. The only thing wrong is that the tones are jacked up. He
was the original owner and told me that one day he decided to play it
after a little while of inactivity and it powered up perfectly, but
when he pressed a key it sounded messed up. He said that his friend
told him that it could possibly be something wrong with an internal
battery? I am not technical at all, but I've never heard of this. But
if it's true it sounds easy and inexpensive to fix. I got it for
nothing and it looks beautiful! The owner is an orchestra leader and
he is in his sixties, i trust him, but still am clueless? If you have
any info please fill me in. Do you know anything about internal
batteries?

much respect,

aaron

This all sounds accurate. That's what happened to my DW8000 when its battery died.
Here's a website with info on how to replace the battery in a Poly 800 II, which I'd imagine
is very similar to a Poly 61. Check it out here:
