Can anyone give me the amps that the power supply for the microarranger needs.
i have purchased a new microarranger but the power supply got missing, i wonder if i can buy a new power supply locally and get done with it.
I know is 12V and the polarity +, beacuse it comes on the manual, but dosent say anything about the amps.
Can anyone advice me what should i be looking for to this new power supply?
Thanks

If the Microarranger uses 9 Watts and the voltage is 12 volts, divide the watts by the volts (Ohms Law), and this will be the current (amps) that the keyboard needs. Therefore, 9 (watts) divided by 12 (volts) = 0.75 (amps). Therefore, the Microarranger will need a 12 volt power supply that provides a minimum of three quarters of an amp. It is okay to use a power supply rated at more than 0.75 amps (750 Milliamps), but do not use a power supply with a higher voltage rating than 12 volts.
