Hi Chip,

Yes, I agree with Godfrey, it definitely looks like a
high frequency unit. Seems like they usually use around
10 kHz  to 20 kHz to drive the primary coil of this type
of "flyback on steroids". The drawback is that you have
a more complex primary drive circuitry than with a stan-
dard 60 Hz unit - i.e. you can't just hook 'er directly into 
your househould service mains in series with a ballast and 
start "sparking away" ;^) Definitely more portable than its
500 lb., 60 hZ fed, iron cored counterpart, though. Person-
ally, I kind of like the "old timey" beefy iron cored units,
though, as they're simpler to wire up and they're built like 
Ft. Knox!
