Korg Poly800/EX800 Users

hey,
i just gt a poly 800 and i need to find an adapter.  The batteries run 
out to quick, and my universal won't work.  Does anyone know where i 
can get one that will work.  
thanks,
andy

I use a Radioshack universal on mine and it works fine. Are you sure you just don't have the 
polarity reversed?

i have the polarity right, bcause it does power up, it is just that 
when i hit a note it changes pitch, and is very wobbly.  It might not 
be the adapter, it might just be my poly 800 is messed up.  but the 
batteries worked for the first 15 minutes, then i went to turn it 
back on an 30 min later, and the pitch wobble started back.
do you have any idea whats wrong?
thanks,

What's the current rating of the universal? Most of
the ones I've seen aren't very high. I'd go with a
nice brawny one like 800mA or 1A and dedicated 9V. And
it's positive sleeve/ negative tip.

Once you're sure the power's right and you still have
the problem, it could be the joystick or its reading
circuitry. Contact cleaner followed by working the
stick all around might do it. Or, this thing is full
of ribbon cables, wire harnesses  and connectors, and
there could be a loose or oxidized one. Good luck,
simple things first!

hey,
the current is 300mA.  i can record the crazy sounds this thing makes 
if it will help anyone identify the problem.
thanks

if you have a universal, it should work. maybe you have the polarity set wrong. i have 2 universals and they both work with any keys i play.

300ma is probably too low. I know the one I'm using is a 1A. The low current could be 
causing your problems.

The radio shcack 9v adapter for the sega genesis works perfectly, the
polarity is correct, the connector fits snug, and it's got plenty of
power to keep the poly from freaking out (Like it does when it's low
on battery or you're running it off a cordless phone adapter :)

well, i went to radio shack today and tried out an 800mA adapter, and 
it still made those crazy noises!!!! so i guess it must be something 
else besides the power supply.  if anyone has any ideas let me know.  
and thanks everyone fortrying to help me!!

May be i'm wrong but do you check the parameter of your patches?  I 
had a similar problem with my poly MKI.  I don't have a back up 
battery, so when the poly was power down I loose my patches and the 
parameters was all messed up, strange values appears and the poly made 
crazy noises. If it is the case you just have to put back the factory 
patches into your synth. Hope it will fix your problem.
Good luck
Bernard

You don't need to put back the factory patches. you just need to get
SOMETHING in there. Sit down with it and make a patch or three. Mine
wiped out 2 banks (70 and 80 i think) when it's batteries went low.

I always get my backup PS adapters at goodwill or salvation army from $.50 to $5.00. They usually have a box of em to sort through. find one that matches your volts (9v for a korg Poly800) and preferabbly match the milliamps too. If the polarity is reversed, you can always cut the cord at one end and reverse the wires to switch polarity which is what I had to do on my poly800 because it's polarity is different than most 9v adapters....
 
Or go to Radioshack and buy a universal adapter for $12-$20 that comes with a variety of adapter plugs and you can adjust the voltage and polarity on those. Good luck, Joseph
