Re: [TCML] My first Tesla

[Simon Dodd <Simon@xxxxxxxxxxxxxxxx>]

Thanks for that, I'm assuming you are talking about the Static Gap Primary
LTR Capacitance equation, if so, The 1.4 x Cres would be in place of the NST
current but how would I find the AC line frequency? I am running from a 12V
battery...

Thanks again for your continued help
