I recently inherited one of these with no replacement coils. These are becoming hard to find and although I typically dont use variable voltage setups or any clearomizer id like to figure out how to rebhild 1 of these. I have been using it with a kayfun but any1 know if i take the gaurd off what the possible clearance would be or if anyone has even tried that on the vtr? From the very limeted videos ive only seen people say they are not rebuildable for 1 reason or another. Any help is appreciated. Thanks in advance.
