Hi Tristan,
I put the resistors just before the gap in each leg. These will
swamp out the ringing of the bypass cap and the chokes. I also believe that
they help quenching by isolating the gap from the impedances in the charging
circuit.
The resistors you mention should work ok. Not sure what the values
of the other components are in you system so hard to say for sure.
I have two papers on this subject at my website which may help in
explaining this:
"Design of a Neon Sign Transformer Protection Network for Tesla Coil Primary
Circuit Applications"
and
"Testing of a RLC Neon Transformer Protection Network for Tesla Coil Primary
Circuit Applications"
www.peakpeak-dot-com/~terryf/tesla/experiments.html
The last paper was rather negative on the RLC circuit but I use too
small of an R for that test in retrospect.
Note that I put the charging circuit across the primary cap in these
tests as a worst case condition. You always want the charging circuit
across the gap in a real coil system.
Regards,
Terry Fritz
