dear ricardo, what do you mean by producing sparkgaps? You mean sparks?? Sparkgaps are the things sparks jump in between! I posted the question about using a rumkorff inductor/coil as a energizer for a teslacoil, while I thought: if it succeeds, I have a safe low power way of supplying my teslacoil. Allthough it works to let the rumkorff produce a high voltage, it supplies only a very low (<1 or 2 mA!) current. Since you need high current to charge the capacitors quickly and you don't want to have a to high voltage (output rumkorff can be easily >90 KV!!!) while your caps will fail easily, often NST (neon sign transformers), Pole Pigs (transformers with a high voltage connection on top and constructed using high top insulators) or Plate transformers are used. They all supply high currents (30mA....2000mA) by reasonable voltages (9..30 KV). See?? On the other hand Rumkorffs are rather seldom found, and a nice introduction help in to the high voltage area. Please take care of cap's (capacitors) charged by this low current source while the voltage can reach dangerously high values as well as the current (charge) stored!!
