Are all SH-101's the same?

[rhythmking90]

Just got an SH-101, but without the power supply. I'm going to pick up an old Boss PSA-120.

However, the little panel on the back of the 101 is nowhere to be seen (the one I've seen on other vintage synths like SH-2) that has the voltage/info on it- i.e., 100V/Japanese, or 117V/American.

I've been researching this but can't really find an answer- are all 101's the same in regards to different markets, since the power supply is external? Or were some 101's made for the Japanese market, and some for the American market? Will I need a voltage/power converter?

I am located in the Northeast United States (which is where I will be using the 101).

You need a 9vc 500ma DC center negative.
Your Boss PSA-120 will do a perfect job.

Synths that run on a power brick/wall wart don't require specific voltages. The power brick, however, does.

We just use a 1000mA universal power adapter, which is a much better purchase than a Boss PSA power adapter since you can use it on a ton of stuff. You just need to make sure you select the correct voltage before you turn on the device.
