If I remember right from school(30+ years ago): If you put the 120 volt line
current through a full wave bridge what you get out is essentially a 60 volt
120 Hz signal on top of 60 volts DC. The current from the DC component should
be large enough to saturate the core and give just a tiny 120 Hz AC current
out the secondary. On the other hand if you put the xfmr OUTPUT through a
rectifier bridge you get a nice 120pps to your spark gap and coil primary.
