MZ-80a US Power Supply

Hello everyone!
Has anyone any suggestions on replacing the 220v PSU in my MZ-80a with a 120v one? Can I just get a Meanwell type and set it up? Is it just 12v 5v rails or is something else needed?
Thanks in advance.

Better, one being able to accept 100-240V to deliver 5V/4A
This one is around 5A:

According to the service manual it uses 5v and 12v so that one would not work

Ah sorry!!!! I thought about MZ-700 so yeah you may need 5V and 12V. And I wonder whether -5V may also be needed. But anyway, there are Meanwell PSUs which can provide those different voltages.

Thanks! Yes I need to check dimensions as well as its a pretty small area inside the case to fit one in. I really wish they had just made a shunt for dual voltages.
