Hi, the "transformer" is just two Coils on a core and is for Filtering the Voltage even better.
You will find that kind of circut in Higher End Switching Power Supplys.
I actually ended up simply Copying the Input Stage of an Old PC Power Supply and also using most of its parts for the built.
Since i am not native Speaker i do not know, how to call that "transformer" exactly.
In german it is "Drossel", maybe look it up, if you feel the need for that.

Hi...i am a new user here. I would like to suggest to add a Fuse and a 100K Resistor to Discharge your Capacitors to Avoid Harm from Loaded Caps when unpluged.The Diagram pictured Below is what i use for LED, donīt Know if that would work with your electronic ballast and your type of Lamps.If the Ballast unit is not too expensive, and easily replaceable, maybe just try it or Work your Way up with the Voltage with a variac.
