I will give a short summary, The LM317 here configured for around 6.4V DC. The Q3 BC547 limits the current, you can select [...]
This is an electronic choke for a Conventional Fluorescent Lamp. This was an application note of MJE13005 a High Voltage Switching NPN Power Transistor. I Might have modified it. This was very popular in the early days, The Coil Winding and Ferrite is very Critical design.
The diodes, npn transistor and caps are high voltage [...]
