Hi guys, I'm traveling abroad to south America where the standard outlet power is going to be 115 VAC. I'm bringing an amp with a solid state smps rated from 190 - 240 VAC. Is there a converter to use to go from 115 to 220 vac? something like this or other options? Weight is a big consideration! http://www.quick220.com/-A220-15D.html Other ideas? Thanks, Paul, kg7hf
