Hi Shaun, Steve,
Although synchronous firing (w/LTR tank capacitor) can be quite advantageous for the rather limited available power with a typical NST driven spark gap coil system, from personal experience, I have found the output can be just as impressive with asynchronous spark gap operation and higher bps ranges w/ a smaller than resonant tank capacitor with the more copious available power with PT or pole pig driven spark gap coil systems. And it’s a whole lot easier! 😉
Just my $.02,
David
