I currently have an evic head (not sure of the version) on a kir fanis body and top cap. The evic is showing constant shorts when any atty is screwed on. I have given up on the evic.... Now is there another head that will screw on in its place that will allow me to re-use the kir fanis body and top cap. I'm over the variable wattage concept VV would be fine. Any ideas?
