I have yet to take apart one of the coils that my Summa came with but I feel I will soon be trying to rebuild at least one of the coils (BECAUSE THEY ARE 5 BUCKS EACH!!!). I also have yet to see anyone anywhere offer any info on taking one apart or rebuilding. I have plenty of experience under my belt with rtas, rdas, and well rebuilding everything else I come across because I'm cheap lol. I just wanted to see if anyone has any experience with these massive ASC coils??
