    10:20 Never tried shorting it with a finger but I've gotten a few shocks grabbing old ballast contacts with both hands. It tickles but I've never gotten burned. One time the shock was strong enough to cause a muscle spasm and I dropped the 4ft bulb.

    Hi Mehdi. The coil inside the CFL light you opened is an inductor. Not a transformer. It's the inductor for the buck-boost circuits used in the LED lightings. They don't have transformers.

    Mehdi, almost all older analog electronic devices involving audio require DC voltage internally (even if fed by an AC Mains power source), especially if there are any vacuum tubes/valves, e.g., the CRT tube or tubes for audio or signal amplification. Even the relatively newer examples that utilize transistors (operating in Class A or Class AB) configuration will require DC voltages to do their work. Now, Mehdi you are the Master and I’m just a self taught music gear tech. What I know is obsolete for most modern applications, as the new devices are all digital. Sadly, most Electric Engineers don’t have much experience with this type of antiquated analog circuitry and it’s no longer taught as part of the curriculum in most University EE programs. I’m hoping the old school tech and the following suggestions are of benefit for you. Try scoring sometimes old, pre-1990’s TV sets or computer CRT display monitors. They are a wealth of parts, especially for building your high voltage power supply. Another idea is an SMPS. Using Power MOSFETs, LC and/or LRC networks, you should be able to create a stable, smooth high voltage AC output, suitable for your purposes and not need a specialized transformer. As a last thought, have you considered winding your own transformers? A burnt out transformer with a two-piece, sized-sufficient core is cheap (generally free if you discover one) and you could simply rewind the ferro-metallic core to your own specs. The appropriate wire is available from a bunch of different vendors. You don’t have to wind it manually either. I used to wind my own electric guitar pickups on a pickup winding machine I built myself. Same concept. Mehdi, I’m 105% confident that could build a transformer core winding machine in your sleep on account of you talent, advanced education and manifold skill set. Please look into revisiting this topic, even if you have a commercial High Voltage PS currently. Maybe the ideas I shared with you will help you succeed.
