Re: [TCML] Largest Secondary Coil "Drivable" by Primary Circuit

Brandon,

The toroid size should follow the input power, not the secondary 
size.  If you keep the input power the same, but use a larger secondary,
you should not use a larger toroid (unless the toroid was too small
for the power in the first place).  If you increase both the input power and
the secondary size, then the toroid size should also be increased.
If you double the input power, then the toroid should be made
1.4 times larger approximately.  For example if the original input
power used a 13" toroid, then when doubling the input power, 
you'd use an 18" toroid... just a rule of thumb.  The spark length
should also increase about 1.4 times if you double the input power.
If the original spark length was 40" then the new spark length
using double the input power might be 56" or so.

Hi John,

When I mention spark quality, I mean how long or bright the breakout is.

That's some really nice information there, I may have to save this email! So

if you want the biggest, brightest breakout in town, you shouldn't worry

about secondary and topload size (unless you fear bad quality in secondary

arc length comparison) being as big as possible, and just make sure it isn't

too small. Increasing secondary size will not affect spark length unless the

secondary is too small to begin with (indicated by racing sparks).

And if you're to increase the topload size, it should follow the same

effects as the secondary coil, right?

Thanks John,

Brandon
