Tags: Ac Adapter, Ac Power Adapter, Amp, Keyboard Yamaha, Power TransformerI have a Yamaha keyboard for which the AC power adapter (transformer, the little black box) seems to be nonfunctional.
The original transformer puts out 700mA current. I found another transformer in my house that puts out the same voltage (12V) but 800mA current.
Is it okay to use that one to power my keyboard, or do I risk frying something?

Ray M says:
Yes – as long as the voltage is correct, you can use one with a higher current rating.
Things that have to match exactly:
voltage – also if AC or DC
tip size
tip polarity (which part of the plug is +, which -)
Current or amperage can be higher, as long as the minimum is met.
