For what it's worth, my small coil with 12" by 3" OD toroid
on top gives about 24 to 25" streamers with 6 amps input at 120
volts. Don't have a wattmeter that will go high enough to measure
actual power. Gap is "5 cylinder" a la TCBOR, resonant frequency
is about 280 kHz, and primary capacitance about 0.009 ufd of
"door knob capacitors", which get hot in a hurry. Feeding from
a 12 k
12 kV, 60 ma transformer. Gap is set so that it just fires without
the primary connected.
