Hello Everyone! I'm new here and I hope someone can help me. I was given an old Yamaha PSR 500 but it needs a new power cord. I found one on amazon but it has 12 volt, 2 amp output where mine has a 10 volt, 1 amp output. Is this going to work?

It MIGHT work or it MIGHT fry your Yamaha.

I wouldn't risk it.

Contact Yamaha support and order the correct part direct from the manufacturer.

According to the PSR-400/PSR-500 Owner's Guide, they use the PA-5 power adapter, which is discontinued. The Yamaha web site doesn't list the specifications for the PA-5 power adapter, but does have a picture of it which, when enlarged, shows "OUTPUT: DC12V 1.5A"-- it's a little blurry, but that agrees with the description of the PA-5 that can be found in the PSR-500M Owner's Guide. So it sounds like the power adapter you were given with the PSR-500 was slightly out-of-spec from the preferred adapter. However, the Specifications on page 40 of the PSR-400/PSR-500 Owner's Guide says that the "Rated Voltage" is "DC 9~12V," so I guess the power adapter you were given was within the instrument's tolerance.

If you want to get something with the same specs as the old PA-5, you can get the PA150 power adapter from Yamaha, which replaces the old PA-5. Your local Yamaha dealer may have one, or you can order a PA150 or PA150MM from Amazon (the PA150MM seems to be the same as the PA150 but costs less for some reason).

Edit: PS-- If you don't already have a pair of headphones and a foot controller for the PSR-500, and if you don't mind spending a little more money, then you might want to consider getting the SKD2 Survival Kit rather than just a power adapter, since it includes the PA150 power adapter, the FC5 foot switch, and a pair of stereo headphones. The headphones are cheap plastic and shouldn't be handled roughly or they might break, but they're comfortable, sound okay, and most importantly they have the larger-size audio plug that's required for the keyboard (most headphones these days have the smaller-size audio plug that fits the audio-in jacks on most computers) so that means you won't have to buy an audio adapter for the plug. And the foot switch lets you turn sustain on or off-- it isn't nearly as nice as the FC4 foot pedal, but it does the job.

One other thing ton make certain of is whether or not the power supply is regulated.'

Using an unregulated supply on a keyboard requiring a regulated supply will blow it out quicker than you can say "Bob's your uncle."
