PS 555

Posted by: Mauricio Ichi on 22 October 2018

Hi guys,
I'm thinking of doing an up grade on my DAC. There was an opportunity for a PS555 220V. My question is if I can turn this PS to 120V.
Thank you in advance for your help.

If you scroll his post the question is there, he wants to know if the mains input voltage can be changed from 230 to 120 on a Naim PSU.

My doubt was if the toroid did not allow the voltage change.
So just change the posts on the trafo, okay?

It's a question for Naim tech support and for them to make the change.

I think you need to send the 555 to the factory to be adjusted.

It would need to be changed either by the Naim factory or by a Naim distributor with the service facility and experience to do so - it is definitely not a DIY job.

Otherwise your best bet is to purchase a 555PS for the American 115V market.
