Ok, so here it is. I have a Sony Vaio laptop, brand new top of the line, with an Indigo IO soundcard, a ART Tube MP Studio V3 tube pre-amp, and a Audio Technica 3035 condensor mic. Software I will be using is Audacity. Project goals, to record a few solo acoustic guitar songs and get a decent sound. The Problem: I have recently relocated to China(temporarily) and have questions about using power adaptors; I don't want to fry my equipment. I have an adaptor that works for the laptop and the mic requires phantom power from the pre-amp. This is where I have questions. The preamp specs requires a 115 VAC and 50 Mhz to 60 Mhz using a 9V adaptor. I have found a power adaptor for my son's X Box that works, its specs are 115 VAC and 50 to 60 Mhz. The only specs for the X Box adaptor are "Output AC 100-120 V/ 200 Watts" I think I can plug the adaptor for my preamp into the adaptor I am using for the XBox, but I want to get a second and more educated opinion so that I do not destroy my equipment. Any advise or suggestions on how to figure this out? Any help would be greatly appreciated.
