Ok my band is a cover band that plays mainly frat parties. My friend has his own PA and runs sound for us. This summer he is going to be getting subs and running a boatload of power to them, which means combined with everything else we power in the band your standard 15A or 20A circuit isn't going to provide enough current. We were thinking of hooking up some sort of rig that takes the 30A 220V outlet that the dryer is plugged into and steps it down to 120V and running everything off of that. I've seen some bands tap directly into the breaker box with big alligator clips to accomplish the same thing, but that's a little too dangerous for my taste. My question is, would it be that hard to make something like this? Would I need more than a transformer and some outlets wired in parallel to the secondary of the xformer? And how much should I expect a transformer that can handle that amount of current to cost?
