Hi,

I apologize for the OT but need some help finding a schematic of a power supply with a pot for varying the current from 0 to about 6 amps.

I've built many fixed and variable voltage supplies with LM78XX and LM317's before but I don't know how to build a variable current one.

I did Google for this and didn't find what I was looking for so if you know of any please let me know.

Thanks,

Sam
