NAOMI PSU

[Mr-Megalo]

dont know which forum to ask this in, just got me a NAOMI setup with GD drive etc and Guilty Gear XX:MC also included is the 3.3v PSU which is 110v , thats not a problem as I can tap 110 from my cab  but what is puzzling me is a little extra thing that I wasnt expecting,  I'll describe it as best I can, it looks like 2 electromagnetic coils wrapped together with connectors that match up for the PSU, so im like " wtf? " any of you guys in here offer any advice ?  

*edit* no worrys worked out what it is, its to power the stereo amp that came with my NAOMI  which I dont need to use as my cab allready has a better kit installed, looks like i got more spares, mods feel free to delete this thread if you like, tar muchly anyways

i would try searching for a manual.  If not online, then maybe if you have a local arcade "dealer" around.  Perhaps they will have some advice.

Do you have a pic you can upload here?

Otherwise, maybe you could beg Guru  He might be able to help.
