Hi All, I'm "new" to this list on this email address(i used to be ayang01-at-earthlink-dot-net) My question is for all those who have tried to depot and enhance an NST for more output. Yesterday while trying this out, i got arcing between the secondary and the Core. What kind of insulations can i use to prevent this arcing?? I'm hoping to stay away from oils of anytype, but i might have to use those if i can't resolve this arcing problem. Thanks -Alan
