Re: [TCML] Tank Circuit Design

[G Hunter <dogbrain_39560@xxxxxxxxx>]

It matters.  I suggest you place the spark gap in parallel with the power supply, and the tank capacitor in series.  In this way, the spark gap can pull double duty as a voltage limiter.  This is especially critical for tesla coils based on neon sign transformers, as NSTs are relatively fragile and are easily ruined by HV transients.

For a more detailed explanation with supporting data, please see the TCML archive.

Cheers,

Greg
