Well, I do have a car battery in the basement hooked to my backup sump pump but it's registering 13.2V and I am a little uneasy about sending too much voltage into the keyboard. Seems like there is a risk no matter which way I go.
As mentioned I got the computer power supply hack to work with the keyboard, but then on a Korg forum someone made this comment regarding the power supply:
It's always been my understanding that power supplies technically do not put out amperage and the connected device uses only as much as it...
Thank you for your replies. Right now I am looking into a tutorial on hacking a PC power supply for 12V. It is my understanding that the amperage output is plenty for the keyboard. Does that sound like it would work?

Kind of an emergency situation here. I am with a band and the power supply to the electric keyboard died last night. They have a gig tonight and nobody sells replacement power supplies locally.
I am wondering if we can find another 12VDC 3.5A source (assuming unswitched) if that will work...
Thanks for the reply. My mixer has a direct out for each channel so I can send only the kick drum channel to the strobe controller. I will give your suggestion a shot and see what happens. I would imagine that I could also use the potentiometer to find the optimum resistance and then replace...
Hi, I don't know if this is the right place to ask this question or not but I'll try...
