Strange events and me coil unexplained

Hey everyone,
   Last night I ran my 6.5" coil at approximatly 5 Kw. 14.4 Kv. My air 
choaks melted. They were wound with 18 AWG insulated wire. Even the PVC 
core melted and twisted. How is this possible, there should only be 
millamps on the HV side ? My capacitance has also increased. I made 
these caps over a year ago. Each cap is .026 uf. I have 4 in the 
circuit, two each in parallel and then these two circuits are in series. 
Ordinarly I'm taped out with the large top load at the 13 th. or 14th. 
turn. Last night I had to tap in to the 9th. turn ! A few weeks ago I 
move the coil outside and noticed that I had to tap in. I attributed 
this to ground clutter. Could the caps still be setteling ?
The calculated value of these caps were .026 uf. They had a measured 
value of about .024 uf. They are poly plate caps. Does anyone have 
anyone have any ideas about the RF choaks or the the caps ?
