Mike; The condencer has a point saving property, but that is a minor
job.Just like the TC capacitor you can get a spark to transpher to the
secondary with out the trouble of a capacitor, but streamers no. Take a car
coil and sit down with a 9v radio battery. test it without the capacitor,
then with the capacitor then with the capacitor of different values. You
will see for your self the presents of the capacitor and the value of the
capacitor makes a big difference on spark size. If careless you may find out
why the car hood open up all the way and isn't hinged from the side as they
once were with a metal rail to stop your head when it pops up suddenly.
