Hi Alonzo, Here is Bob Lee, poster of the current limiter made with two parts. The LM 317T is ok, RS part # 276-1778. The potentiometer can be any pot with a one or two watt rating, usually its a "carbon element, 1 watt, linear pot". However a plastic element pot will also work. The pot should be about 2 or 3 bucks. Remember its adjustable so even a 500 ohm or a 1K ohm will do the job. The key word here is "linear", don`t get an audio taper. Don`t have the RS part # at hand, will send it if I do find it. Can`t even find my catalog.:-) Bless you Bob Lee -- oozing on the muggy shore of the gulf coast [email protected] -- The silver-list is a moderated forum for discussion of colloidal silver.
