Re: [TCML] Racing arcs and primary resonances

[Futuret <futuret@xxxxxxx>]

Not sure what you're saying about being driven harder.  In the
case I mentioned.  There were no racing sparks at full power until
the gap heated up for 10 seconds or so, then the racing sparks
became progressively worse within a few seconds until the 
secondary was covered with a mass of racing sparks.  If I then
let the gap cool down, and went to full power again, the process
repeated.

Of course, a simpler explanation of an overheated static gap causing racing 

arcs is that it is being driven harder...
