The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.

Thats called an equi-drive configuration and is perfectly functional. If I remember correctly, that's actually the way Tesla preferred his setup. I've also heard that using that config allows a more pure ring-down of the primary circuit.

FYI, Kirchoff's current law says it doesn't matter what order the L's and C's are in... in fact you could break your primary into multiple segments with capacitors in series with them (provided the mutual coupling between windings was not effected). All that matters is that to total ESL and ESC (did i just make that up? equivalent series capacitance) are the same as the lumped model where you have just 1 L and 1 C.
I never understood this BS about equidrive giving some sort of advantage. I have yet to hear a credible explanation, other than "Tesla said so".

Would this configuration work in a drsstc ? But i think as steve pointed out , it should not give any sort of advantage. Maybe it would just ad more to total ESL cause of additional wires :P

Meh, the only advantage I could ever see is that you would block DC from the primary and thus reduce the shock hazard from it... still that would be a poor excuse for touching the primary in any case.
If it's easy to do I'd go for it, as there's nothing to lose in any case.
Sometimes I'd prefer it (if I have 2 DC blocking caps of 250V, I'd rather put each of them onto other H bridge leg than both in series on one leg. )

Blocking DC from getting off the primary could actually create a shock hazard if charge remains in the two equi-drive capacitors at the end of a run - Always use bleeder resistors!

Would splitting your primary tank cap work...?
