Does anyone have a schematic for a variable voltage power supply. It will run from 0.1V to 17V @ 2A. I know I will need a 17V 2A transformer, bridge rectifier, several capacitors and resistors and either a rheostat or potentiometer. I can't find any good schematics for what I am looking to build. It will be a tattoo power supply. It will need to have a 1/4 phone plug for footswitch and 1/4 phone plug for clip cord (machine attachment). Our machines run anywhere from 5.5 V to 12 V. Any help would be greatly appreciated.
Thanks,
Anthony
