Re: [TCML] Strike rail hits and loud bangs

[bartb <bartb@xxxxxxxxxxxxxxxx>]

Let me guess Steve, the tap point had a little more L (slightly higher 
inductance). Am I right?

Also, yes you can tune a coil into self destruction. Tune it to where 
it's "barely" in tune and with slightly high coupling. This will 
compound into a myriad of racing sparks and sure self destruction is 
possible (a shorted secondary turn or similar issue). Been there and 
done that. You can even over power a coil and turn it into a flaming 
puff of smoke (I haven't done that yet [knock on wood]).

Take care,
Bart
