Polarity Question for iMP-350 (AC Adaptor)

[Lightloch]

Hello,

Because the iMP-350 I just purchased on eBay uses a completely incompatible plug (voltage, current, etc.), I had to buy a universal AC adaptor for it. So far everything is set (4.5v, 500mAH, 110v), but my one last obstacle is what polarity to set the DC-in tip to.

This is where I hope one of you can help me out, as I am hopeless when it comes to power ratings and what not -

The original charger (label on the back) states that adaptor's polarity is the following (listed from left to right as shown below):

(-)----(0----(+)

EDIT: Thanks NPswimdude500 for the picture. My charger's polarity diagram is identical to the one in the photo linked above (for further clarification).

Now, with this information, should I set the DC-in tip which goes into the iMP-350 to be negative or positive? I am wary about this because I do not wish to blow the thing up when it's brand-new .

Thanks for any assistance!

From your diagram it looks like the tip is positive.

Thanks for your advice - the universal adaptor works great!
