T POWER 12V Ac Adapter for KORG KA-310 Korg Kaoss Pad KP2 KP3 KP-2 KP-3 Dynamic Effects SP170 SP170BK Digital Piano Keyboard DSA-0151AD-12A 500405015300 X50 61-Key microX R3 MR-1000

This works with Korg EK-50. Seems well built (pastic, but quality plastic). So far no issues.Note: It was a frustration that you can't get the brand adaptor even from Korg! The specific model is KA-390. Their accessories supplier didn't have them on stock, and don't know when will they be in stock. Had I known this, I would never chosen Korg. (@Korg, please take note).

It worked great for my Korg R3

Was extremely difficult finding a replacement adapter for my Korg EK-50, because I read several articles that say it has to be the right one, or you can permanently damage your keyboard. This one is perfect. The power supply is on the end with the AC prongs, not some brick inbetween. It’s the right item for my model keyboard, at the right price.

Not sure it would work for a Korg X50 keyboard. BUT WORKS PERFECT!

The power supply was super cheap, got here a day early, and works perfectly with my Kaoss Pad KP3 as well as with my Korg R3 Synthesizer! Very satisfied.

Does exactly what it's supposed to. KP3 works fine now. The pin connection is identical to manufacturer's.

Worked great.

Works great, no issues getting here, happy to have my KP3 up and running again!
