I've been using a radio Shack 300mA supply on my korg for the last year without any problems.
But I would agree that having at least 500mA would be preferrable.

there are 1A 9v adapters on ebay everyday for about 5 dollars shipped... I may have to invest in one and upgrade mine.

hello!

OH MY GOD!

I so hope you didn't listen to ANY of these replies

that suggested 1000 MA, or 650 MA, or 600MA,

or anything over 300 MilliAmps.

from the Korg website:

*9 VOLT 300 Milliamps*

Part/Model number:
KAC9500

center plug is 2,1 mm.
outer ring of PSU connector is "+" positive.
center tip of PSU connector is "-" negative.

, thats what all the Poly800 eletronics

are rated for, what comes with Poly800 from the factory,

thats what the manual says to use, and the KORG website..

You will damage your little plastic Poly800 seriously if you go above

300MA, maybe not immediately, but it will be all about

melted plastic and burning caps and resistors and PCBs,,,

LOL!!!

those had to be a joke right?

whatever... I hope you didn't melt your KORG...
I just bought this adaptor on eBay for 8.50 USD, and there

are lots more!

hope I wasn't too late for you!

I've been using a radio Shack 300mA supply on my korg for the last year without any problems.
But I would agree that having at least 500mA would be preferrable.

there are 1A 9v adapters on ebay everyday for about 5 dollars shipped... I may have to invest in one and upgrade mine.

>FIZMO is not like Proteus at all. Proteus type are ROMplers and very good ones. I have a Proteus 2000 with additional ROM chips for more sounds. FIZMO is a transwave synthesizer that blends together different sections of base sound waves into new morphing combinations. It's sort of the difference between playing a recording of a violin and playing a violin. Except FIZMO isn't good for violins, while the Proteus is. If I'm explaining that clearly enough. Or maybe closer, Proteus is like playing a recording of a cat, while FIZMO is like playing a cat. Or does that make it more confusing?
