I repaired a 15kv-at-120ma unit using the old chip and soak method. The 
primary is a pair of either 14 or 16 guage wires wound in parallel and 
the secondary is about # 40 guage. I doubt that you could ever burn 
out the primary but I would have serious reservations re the 
secondary. Hope this helps.
