Subject: Re: Spark Gap
As a beginner, I have to ask this. When the main spark gap is supposed to
1 - When the tank capacitor is changed at full voltage (1.4 * transformer VAC)
2 - When the tank capacitor is changed a suitable voltage LOWER than that?
If the correct answer is n.2, so what is the benefit of having a 14 kV
transformer if the capacitor is discharged always at e.g. 8 kV?
With my (supposed) 8kV tank I can get 0.37 inch sparks so that using a, say,
0.15 inch gap would reduce my used voltage to about a 40% of the available...
More, isn't that shorter gap much more difficult to quench than a wider gap?
