Greg,
I'm glad to hear you're back into coiling. Your question is clear.
The primary is generally tuned to the aggregate resonant
frequency of the combined secondary and extra coil. At least
this is true for normal spark gap coils. If a system could be
made to quench extremely quickly, then it might be of some
benefit to tune to the extra coil frequency. At least that's
my understanding. Some sort of electronic quenching
might work. I don't think anyone has tried it yet. There
might be newer information available about this issue
that I'm not aware of.
John

Subject: [TCML] Back again....and Tesla Magnifier Tuning
Hi All,Well after a few years off I'm back into coiling. I've been into coils on and off since the mid 90s and it's great to see the pupman list still going strong! How many members are there these days I wonder?Anyway, I have a magnifier project in mind and am interested to know about the finer details of tuning these beasts. Is the primary normally tuned to match the resonant frequency of the extra coil alone (plus some for streamer/corona loading), or is it tuned to match the aggregate resonant frequency of the combined secondary and extra coil? Or somewhere else completely?! It seems like if the primary + secondary system is truly meant to act as a transformer base driving the extra coil, then the tuning should be closer to that of the extra coil alone than it is to the combined secondary and extra coil system. Hope that makes sense!Any advice would be most appreciated!Regards,Greg._______________________________________________Tesla mailing listTesla@tedward.pupman.comhttps://www.pupman.com/mailman/listinfo/tesla
