Oh good heavens, John, how reckless - shooting from the hip... I'm
proud of you! ;-)

We had a circuit that was similar in a piece of RADAR gear - IIRC the
transformer was pretty standard looking (but then it's been 30+ years).
I think the key here is the the phasing of the two secondaries - with
the core approaching saturation - the mutual coupling would decrease (as
would the inductance itself) and since the phasing is opposed - both
tend to incease the bulb's current...

Am I missing something?
