Yes. I never noted risetime at the time but it's pretty fast. I will 
do this again when I get into the lab and measure it. I am planning 
to take photos of scope waveforms of running primaries, coils etc.

It's pretty clean, even with normal gap + pri Q's but I haven't 
measured it using spectral analysis.
