Korg Poly800/EX800 Users

Hi Rob,

Welcome to the group.

Replacing the backup battery is easy even for someone that has only limited experience with a soldering iron. If you take it to a tech then it should be quite cheap to do. The only thing that complicates matters is that some of the early Poly-800's came out without any solder tabs on the main PCB where the battery is supposed to be soldered in.

1) If you already see a battery present - no problem.
2) If you can see the battery solder pads in the middle of the main board - no problem.

But, if you can't see the solder tabs let us know because we can put together a simple document that will describe what needs to be done to fit a battery.

Mike

Hi ,
Just sending along a not so short e-mail,
to confirm my membership.

And So.....
My recent acquisition, an old  poly 800, isn't modified( as of yet anyway),
but It seems to basically function OK, dispite a few shortcomings.
I need to get a new battery set up for it .
The internal battery  probably needs to be replaced at this point?
 Also the regular battery compartment, ..the old C batteries, must have leaked all over the place, as I found the" C "battery compartment and it's minuscule connect at the board are presently toast...not much other major damage done as far as i can figure,(hopefully) 
other then some rusty spots here and there on some metal supports inside..

I am able to change parameters etc, and the tape in works,
 though I have not tested the tape out yet..

I had read somewhere on the web, someone had adapted a cordless phone type- rechargeable battery pack to their poly.. instead of the old C s.,  and  that would seem a  very cool idea!

I'd really like to do something, as I hhear that without batteries,  I am unable to store anything I've created on it when I power down, and  it seems to take a while to build sounds that are to my liking..

 I could attempt to use a tape back-up every time I turn it on and want to get my settings back but that doesn't seem like it would be all that spontaneous and seems a bit of a bother.
For right now, it's a very interesting workout in making cool sounds..
and I've found some sound files I'll be able to load and check out,
but I have hopes of it being more funner if I can get it working at least as
it should
and with other possible modifications .

Working on a major repairing/ modifying of this thing myself would seem a poor choice..
as reading  schematics is a little over my head and
working with tiny circuits and a soldering irons is not really my strong suit,
as I have the eyes of Mr Magoo, (plus I am a bit ham handed) 
So  I 'll probably have to send it out to be worked on.
Hopefully  I can  find someone that would be able and want to taclke
 an old troubled poly 800.
(I can't even find someone to comptently  fix my poor old car's horn )

I would welcome any sugestions, ideas or useful info in these regards.

Thanks!
