The goal: I need to be able to play sound on some computers, but the quality doesn't matter much.

The situation: Somehow in our office move, the power adapters for two different sets of speakers got misplaced; now I have two essentially useless sets of speakers, unless I can replace the power adapters...

HOWEVER, I do have some other AC adapters that fit the port (our move was a disorganized mess), but they don't seem to match the specs of the speakers. What should I be aware of if I want to reuse these adapters?

  • Speaker 1: 10 V, 500 mA, 50/60 Hz AC
  • Speaker 2: I can't figure out what spec they're supposed to get, because to the best of my googling they were made in the late 90s and there's no manual posted anywhere online... (Altec Lansing ACS52. The only thing I could find that was even remotely helpful was this archived google image (the original image doesn't even exist, ha!). It's the one on the right, but I can't read it. Speaker image

Other power adapters:

  • 2x 12 V, 500 mA
  • 9 V, 1.5 A
  • 9 V, 1.0 A

What can go wrong if I try to use some of these random power adapters? Should I consider buying a new adapter? Should I just buy some new speakers?

As with any DC power source:

  • Voltage should match (or be very close).
  • Amperage on the source (IE: the adapter) should be the same or larger than what the device purports it requires.
  • The size, shape and polarity of the connectors much match.

If you go too far out of spec, you may/will burn out the power adapter, the device, and in the worst case, the cables start smouldering and you burn down your home. :)
