Input Voltage question for Naomi Amp

[bboycap]

Hi there,

I just got a Naomi AMP set and don't know what the input Voltage for the transformer is? is it a DC or AC input?

Please take a look attached pictures. what do the yellow, black and green color wires mean? I believe green is ground, what about the yellow and black ones?


Thank you so much

I just googled and it seems a 120V AC input. just need someone's help to identify which wire is L and N. Normally, Yellow wire should be L and black wire is N. am i right?

Shouldn’t matter with AC

Yeah, Thanks for reply.

you are right, but i am just curious what the original design is.

I would say Yellow is Live and Black is Neutral, but cannot confirm as I’m not from the States

I think the same as you do. Hope someone can give me a clear answer

Damn Americans... No logic in it

But as it is an Japanese component I would still say that black is neutral...

Just check the schematic from a NNC manual, Black is labeled AC100V(N) and White is AC100V(L)

lol, after checking the Naomi PSU (Part no. 400-5397), the black one is live

it's hard to know the rule XD

check the pic, don't see it mentions color right here

color code 80 = black
color code 50 = white

so in your schematic black in neutral as well

WoW! I didn't realize that there is color code on it. thanks man!
