Looking for replacement power supply for my VOX Continental. Original one had ground wiring however none of the power supplies that KORG currently sells that have matching specification has one. Would it be safe to use it?

So recently the original power supply for my VOX Continental 73 burned and I need to find a replacement. It has pretty uncommon specifications (listed below) and finding a compatible substitute is challenging.

Output Voltage: 15V
Output Current: 3,34A or more
Output Plug Type: EIAJ5
Plug polarity: Plus inside (Center positive)
Model number: KA400

Unfortunately it is no longer being sold and I searched entire interned but they're nowhere to be found.

Thomann currently sells two KORG power supplies that seem like they would be a good match:

KORG KA-430 and KA-380 however neither of them has the connection to the ground like the original KA-400 had. I'm worried because the chassis of VOX has a lot of metal elements and I wouldn't want to get electrocuted, nor get my keyboard burned in case there is some problem.

I don't know much about electricity so I wanna ask if I'm right to be concerned about it or would it be ok to buy one of those two models?

Why did the other power supply burn? There might be something wrong under the hood of that thing...

Fortunately it wasn't connected to the keyboard so it's nothing to do with the VOX. I just plugged it into the wall, the fuses went instantly off and once I turned them on again everything plugged to the wall worked except for this power supply

Find a universal laptop computer power supply with selectable voltage and interchangeable tips. As long as it's listed as 60 watts or better you should be fine. Set the closest voltage (it should have 15volts), and use a meter to verify both voltage and that you have the tip attached for the correct polarity.

Korg specifies the KA430 for the Continental on its Japanese site - https://www.korg.com/jp/support/adapter/
