From what I've researched, swapping the capacitor and the primary spark gap will work for a tesla coil spark gap coil.. However, due to how fragile NST transformers are, you always want the spark gap placed in parallel with the transformer. (preferably after a terry filter and safety gap). NSTs can handle a direct short since they are current limited, but they can't handle the RF power.

Hi Kuba,
1) According to your diagram, Your MMC will work, BUT the resistors are doing nothing because each one is shorted out by the wire connected across it. The resistors must be parallel to the caps or they are useless.
2) Yes, the spark gap shorts out the transformer when it fires. This is as it should be. You want the RF energy going back and forth from the caps to the primary of the TC and NOT back through the power transformer.
Hope this helps,

Here is a better diagram of the MMC http://postimg.org/image/vptl7mjox/
My only question is concerning the position of the spark gap. In most
diagrams of Tesla coils, both outputs of the transformer connect without
any interruption but the cap MMC and the primary coil. The spark gap only
seems to be fired when the circuit cannot hold any more energy. This just
looks a little problematic to me as both ends of the transformer are
connected without the spark gap blocking the connection, but just waiting
for a surge of energy to shoot across the gap. From looking at other
diagrams online, the drawing in the first email should be correct, but I am
just not 100% sure.
