I've been trying to find a place that sells resistance wire in thickness between 0.25~0.30mm. I have some 0.2 and 0.32mm wire that I got from 千石 in Akihabara, and I've made it work. But I've been running into problems with resistance because either I need more wraps or fewer to get the right ohms, and either its too few wraps and I have trouble getting the wick right or too many and it won't fit in my kanger heads. Anyone know where to get the thickness I need here in Japan?
