This electronic circuit is power supply that is a compact, easy to build and use positive variable power supply module. It is ideal for powering any application requiring a DC supply at current levels up to 1.5A.
Diodes D1-4 form a bridge rectifier which converts the AC input voltage into a DC level. They also allow [...]

These transformers are AC Power Supply with 120VAC input and 2kVAC output. Just wire the cores together (the cores are normally one of the High Voltage Terminals) and wire the primaries so they oppose each other. If you don’t get a nice arc from this switch the input leads on one transformer.
This will not arc [...]

Here’s an adjustable power supply that is a positive tension. But we use a negative voltage stabilizer. The circuit is something else but it has a big advantage. We now have the final transistor whose Collector often to the house is not to isolate the cooling plate!.
We can now as the transistor to the closet [...]
