AKAI S1100 Japanese import power advice

Hi all,
I am the proud new owner of an Akai s1100.
However it is a Japanese model so 100v.
I have found a transformer but my concern is that the power in is unpolarised and has no earth !
Is this going to be an issue ?

Cheers.

No, polarization and ground/earth is unlikely to be an issue.
You did not reveal what is the transformer you found?

Does it have a sufficient power rating for your Akai S1100?
That would be my primary concern.

Yes the transformer is a 230-110 50/60Hz
Made by Airlink.

The service manual I found says that the Japanese version takes 32 Watts
So you need a transformer that is good for at least 50W.
I would prefer to use one rated at 100W.
If you use a transformer that is too small then it will overheat and may catch fire and burn down your house. Seriously.

An Akai S1000 or S1100 with a Japanese Transformer will usually have 100v written on the back near the power plug. It may also only have a 2 prong connector without the ground prong.

Here you can see I removed the old plug-in receptacle in order to install a USA 3 prong plugin:


If you open it up, the transformer will have a (J) on it indicating it is for 100volts Japanese power grid.



however, a European 240volt transformer looks like this with (EVBS) on it:



I posted instructions how to install an aftermarket transformer to convert either a Japanese or European Akai S1000/S1100 for use in USA.

Akai s3000xl change voltage

In that thread I explain how to buy a transformer that takes 120 volts input and outputs two 15 volt lines to power the Akai internally. It doesn't cost a whole lot. Perhaps $30 for the transformer. You can buy external step up or step down transformers, but I rather just permanently convert some of my gear to work in USA to avoid catastrophes such as accidentally plugging in a Japanese or European rated transformer into a 120 volt USA socket.
