Ok so currently I am in Australia and have a 2012 ampeg 810av cabinet. I want to run a vintage head with it. I have one that I can buy from the US. My only question is, what kind of power converter will I need. The SVT head is 300w so will that require 300 watts just to run it?. I've read that Australian power sockets run between 220-240 volts, while Americans run at 110-120. Also being a vintage head will it have any troubles running a modern cabinet?. Any help regarding converting voltage would be greatly appreciated. This is must first time dealing with this sort of thing.
