Hi Malcolm,

I thought I accidentally deleted this post, but fortunately I found 
it.  I presume the excessive voltage was at the safety gap???

How wide was the safety gap setting and where was it relative to the 
main gap and the coax and at what end???

Can you describe where the R and C in the filter were in the filter 
and what values they were???

Any idea what the overvoltage frequency was and the resonate 
frequency of the TC??
Also an estimate of the coax length??

Thankyou
