A .05 uf capacitor is exactly an order of magnitude (10 times) too big 
for a 15kv 30ma transformer!  It was very close to a dead short!  
Actually, a dead short will not ruin a new neon sign transformer unless 
y0u leave it shorted for 1/2 hour or more!

I suspect the transformer was very weak for one reason or another.  
Probably another firing of a tesla coil would have also sent it to that 
"big pile of transformers in the sky".  Used neon transformers have often 
been in service for many years for 8-12 hours per day!  If we get used 
transformers, we must expect a degree of inherent weakness.  If new, we 
must realize that a minute of Tesla coil firing can be like a month 
driving a sign.
