When the current is anything but a pure sine wave, there are other things that will affect the timing. Such as when the amplitude of the current is varying. The ring up is the opposite of this:piranha skrev:Terry, Could you explain to me what a ring up signal is.Until now I have been using it as the current ring-up in the primary of a DRSSTC, and as the ring-up in the secondary of both a DRSSTC, and also a classic Tesla Coil.Another thing: It has been suggested that I use an adjustable inductor with a threaded ferrite slug,I don´t have any parts numbers so can´t really comment on it.Anyone got parts nos. for adjustable inductors, in the 0.1 to 5 uH range, and preferably shielded.Cheers, Finn Hammer

But we might want a variable air core inductor? It depends on how well the ferrites will do there. But just a slug might not have saturation problems.
These are cool :) http://www.surplussales.com/Antennas/TransVarInductor.html Terry _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
