This transformer circuit is a low power and low cost alternative to the traditional Variac and Neon Sign transformer, High current setup. The components are available via Ebay and no complicated engineering work is required to make it work. We have the option to use either the module or voltage reduced AC direct to the coil with resistor applied.
