I can say with certainty that the 20A draw is real, if not understated.
It's not sufficient to just say one is using a 15/60.  The other crucial
factors are cap size and whether above-nominal mains voltage (i.e. 140V
from a Variac) was used, though I could not have predicted the current
draw in advance.  I recall that when I tried using a very large cap (.03
or .04uF, don't recall) with a static gap, I couldn't keep the 20A
breaker from tripping.
