I posted in the main audio forum but think I might get more help here so...

I recently acquired some old Altec Lansing speakers... a pair of ACS31's with a subwoofer and a pair of ACS52's, along with two power bricks and a bunch of cables. But I can't find any manuals on the internet so I don't know which adapter goes with which pair of speakers.

I got one white adapter and one bigger black adapter, neither of which indicate which pair of speakers they goes with.

It may not matter but the adapters are quite different so I want to use the right one.

Can anyone help me out?

TIA
