Need Altec Lansing ACS340 power supply help

[mac-g3]

Hi all,

Just bought a late 1990's Altec Lansing ACS340 computer speaker system
(2 satellites and 1 subwoofer) and need to find a workable AC/DC adapter
solution for it. It requires a 13v 4a adapter which is common, but uses
an uncommon round multi pin connector. Anyone have a schematic for this
speaker system or possibly familiar with the power connector layout?

Thanks
AJ

Appreciate the info, but I'm looking more for schematic and power
connector layout info for the ACS340. I'd like to modify a used adapter
found locally of the correct v/a specs to work with it.
