I've been trying to find a replacement for my SL but every one I buy the circular plug that fits into the back of the cradle is to small. I'm thinking the specs of my current adapter are not correct because I'm getting the correct adapters except for that round plug. My original says 5v 500mA.

I even got one from ratshack with the changeable tips but none fit.

Does anyone have a source and item number for this?

Thanks
SJ

P.S. my dealer is long gone
