This is an aftermarket power supply and the actual power supply is pictured, along with pictures of it being measured with a digital multimeter and plugged into a Yamaha CP80, showing that it works.

Returns are only allowed if this unit is defective, not if you bought the wrong one. Please examine the power connector carefully to make sure it is compatible with your piano.
If your piano does not put out a sound after you plug this power supply in, you most likely have electronic problems within your piano, not this power supply. Please do not hesitate to ask for technical assistance with your problem. We will help you solve it!
This aftermarket power supply provides the same voltage rating of the Original Yamaha CP Series power supply. A picture of a Yamaha CP 80's side plate is shown for reference. You can clearly see that the piano requires a DC voltage range of 16-20VDC. Your power supply is in this range and provides CLEANER AND MORE STABLE DC power for your piano. The original power supply was unregulated and had low-quality DC. This power supply is regulated and provides high-quality DC.
Power Supplies compatible in electrical standards in other countries AND OTHER REPLACED CONNECTORS are also available. Contact me for details. FLAT RATE SHIPPING!
