Wow!  You have been using a .01ufd Mylar!!!!!

That will always be a problem!

The following is for all new coilers:

Let's say this one last time!

All- Repeat all- wonderful caps which are in the ideal Tesla coiler range 
(.001-.1ufd -at- 5-30KVDC), that you obtain (most often at hamfests and 
surplus stores) which are in GLASS or WHITE CERAMIC and have metal end 
caps with solder seals and threaded studs, having the geometry of a long 
cylinder with dimensions of no more than 1.5" diameter and a few inches 
long, ARE DEFINITELY MYLARS!  They are DC filters only!  The glass caps 
are most often RED other colors I have seen are GREEN, BLUE, YELLOW.  
These must not be used in Tesla service without a blast shield!  The fact 
that they get hot is a sure indicator that they are mylar.

You have seen what a difference the big ugly monster from CP can do with 
the proper dielectric.  All should learn from this.  A small 
glass/ceramic cap just can't do what the big poly caps can do.
