Hi, i have noticed some problems with my alumium tape covered toroids, 
theres slight arcings beween the peices of tape when I draw an arc off the 
toroid, opon checking with my DMM, many peices of tape are open circuit to 
nearby peices of tape, I assume the glue is acting like an insulator and 
was wondering what exactly I could do short of compleatly redoing it? I was 
thinking mabey a thin copper wire wraped around the outside or inside and 
covered in foil tape (and carfuly slit the edge of each foil tape I add, 
bend it under, and then overlap that with my next peice to make sure the 
additional tape is conductive)
or should i just do a thin copper ring around the outside without any tape 
and just let friction hold it there or say 4 small peices of tape
