I found an Akai SG-01K but the AC adapter it comes with is some foreign one (has thin circular rods as the contacts).

Would anybody know of a way to get one compatible with US power? It's 10V, center positive according to the label on the back.

I haven't been able to find a real Akai one, found one that might work, but I don't know for sure the barrel plug is the right size, and it looks very after market, not sure if it's the safest way to go. https://www.ebay.com/itm/364836232813?mkcid=1 … emis&media=COPY

I'd just splice the cable from the adapter you have to a compatible 10v one.
Does it say the current requirement - you would need one that supplies enough current.

You also want to be VERY sure of the polarity.
If the one you have is 220v and you live in a 120v country, chances are you can power it enough to
verify the polarity before you "cut the plug".

I'm not families with this unit, but failing that, you can usually "figure" out which side is ground ..
taking it apart you can usually see where and how the power is connected, Ground will be obvious
(should go "everywhere") and supply will likely go to a regulator (might be linear or switching)
- almost everything is positive power relative to ground, but there should be capacitors near the
regulator which would be labeled with polarity (and if it they suggest power is negative relative
to ground, most likely you've made a mistake - don't "plug it in" until you are certain!

Thank you for the advice! The adapter it came with is 100-240v, so apparently it's universal. I actually don't have it in hand yet, I was going to try and get an adapter ordered ahead of time.

The pictures show a different plug style than the normal US one, but the seller is saying it's US style, and he's in the US showing it running in the pictures. I guess I'll find out when it gets here.

Once I get it in all quadruple check everything. Even if it is the right style plug there's a chance it's not even really 10v, might be 9 or 12 from some of the listings of supposed "10v compatible " adapters I'm seeing.

Splicing the connector isn't something I'd thought of, that's a great idea if I need to find something else and I'm not sure about the barrel plug.

I know typically Japanese stuff leans toward center negative, but there's a little logo on the back of the unit in the pictures showing a plus sign pointing toward the center and a minus sign toward the surrounding part.

Hey, that sounds like a really easy fix - I'm guessing the wall plug is wrong.
You can get various travel plug adapters - all you need is the right one to adapt the
plug on the adapter you have to one native to your country (I think you said you were
in USA - so to a standard north-american plug would work.

Since it's 100-240v, you don't need an expensive one that converts voltage
(these are usually only for one country - I have a couple European to N.A. which have
an inbuilt step-down transformer that only works 220->120v and one which seems
to have some sort of switching AC supply which can handle a number of different
source voltages) - these are pricey and since the adapter you have will work on 120v
all you want is a simple "plus adapter" which will plug into North America, and let
your adapter plug in to it (nothing other then metal components needed)

And if you really want it fast/cheap (I've done this 😀 - just solder a cord with a N.A.
plug on the end to the prongs on the one you have - then wrap them very completely
with black electrical tape, or otherwise insure that the exposed soldered prongs
are well insulated.
