Wiring is less cheated than others. It has coil L2 for blocking HF interference and capacitor C1 for voltage 1200V, which is very much stressed. Original transistors are not available on our market. If doesn’t matter size of case TO220, it’s possible to use transistors MJE13007. Mechanical construction Lamp is usually compounded of two parts. Photography of opened Philips lamp.
