I have a Power Station 3, but it does not have 4-digit model number, unless you're referring to something inside the case. I have a Power Station 4 as well (several actually), which was the standard supply for a number of AA components and is interchangeable with the PS 3 (the 3 was an extra cost upgrade). Both have the same 6-pin connector, though the cords on the PS 3 are detachable and those on the PS 4 are captive. The PS 4 says:
"SEC. #1: +/- 18VDC @ 250mA
SEC. #2: +/- 8VDC @ 250mA"
These are sitting in my garage, so if you want one, email me and let's discuss.
