I have three sets of used computer speakers that don't have an adapter, and I can't figure out what kind of adapter they require. And I'm well aware of the fact that these speakers aren't that great, but I can't afford to care. I was hoping someone could help me figure out what adapter I can use. Here are the speaker specs:
1) Dell A215
12V - 0.5A
Caution: This shall be used with power supply, Mfr. Leader Electronics type 41120050-C5 or Hon Kwang Electronics type HKA-1250EC-230, for CE only.
These adapters seem to be 230 volt and meant for use overseas, not in the U.S.
2) HP/Polk Audio - part number 5183-0171 and 5183-0172 - 9V
I think these speakers were meant to be used in the UK.
I tried contacting Polk Audio and HP, but they have no information on these speakers as they're from 1997 or 1998.
3) GCS-100 - 9V - I think these may be MidiLand speakers.
Can I even use the Dell and HP speakers here in the U.S.? None of the speakers indicate anything about the polarity and I don't know if it makes a difference about the mA. For example, I may have a 9V adapter that is 300 mA and I might have a 9V adapter that is 1000 mA. Can I use either one? And what about the watts? I'm sure I have an adapter that will work, I just want to make sure I use the right one so nothing gets damaged, but I don't know what to use.
