This review is from: Yamaha YPG-235 76-key Portable Grand Graded-Action USB Keyboard (Electronics)
I took piano lessons 50 years ago and got this crazy idea that I wanted to play again. So I researched keyboards and read a lot of reviews. I didn't care about the bells and whistles, and it has lots; I wanted something that had keys that looked like a piano, felt like a piano, and sounded like a piano but didn't cost like a piano. The Yamaha 235 is exactly what I was looking for. It is amazing how much like a piano it feels and sounds. I chose 76 keys because I thought 61 would be limiting, and 88 was more than I would use and so far that is good. I ordered a power adapter because it was recommended, but the keyboard came before the power supply, so I used a similar AC adapter I had on another electronic device. As far as I can see it is working perfectly.

"so I used a similar AC adapter I had on another electronic device."
- You'll want to be careful of this. On both the power-supply and the device, you'll see the power specifications.
* VOLTAGE (ex. 12V) needs to be the same on both the power-supply and the device. Depending on the device, you can sometimes be off by 0.5, 1, or even more volts, but be careful: using the wrong voltage can destroy your device.
* CURRENT (or AMPERAGE/AMPS, ex. 800mA) must be LARGER on the POWER-SUPPLY than it is on the device. The current listed on the power-supply is actually the maximum it can handle - going lower is fine, but anything larger will cause the power-supply to overheat and possibly die. Note that 1000mA = 1A
* WATTAGE (or WATTS, ex. 15W) is simply voltage times current, so if one or the other is missing, you can calculate it using this.
And of course, it will only work if the plug fits :)
