Just a  quick question. I'm building my first Tesla coil and have seen at 
least  two topologies: 1) main capacitor across NST secondary followed by 
series  spark gap. 2) spark gap across NST secondary followed by series  
capacitor.  I will be using the Terry Fritz protection filter  directly after 
the NST. Any recommendations on which topology to  use?

Thank you.



Hi Bob,
 
While either configuration will work, the body of evidence indicates that  
NST's that have the gap across the secondary, on average, enjoy significantly  
longer life spans than those with the capacitor across the secondary. Check the 
 archives for the technical explanation of stresses, etc.
