Arthur, My generator setup for colloidal gold is an an underwater arc powered by a 15kv 60ma neon sign transformer. I am currently experimenting with different size batch containers of 1 qt and 1 gal. I'm not aware of anyone producing CS by this method. "Ole Bob" has tested this method for CS and gotten very large particles.
I have seen claims that some LVDC generators can produce colloidal gold, and I do not believe them. Using 15kv to run the arc it takes about 5 hours or more produce colloidal gold to a good color (color changes while generating from violet in low concentration to different shades of blue as it becomes more concentrated). I don't know of any other way to make it. Others may, and if so please share your process. "Ole Bob" is investigating a new process now, and I'm sure he will share his findings with whomever is interested. The generators I have seen that are designed to produce colloidal gold sell for upwards of $900. I have invested about $300-$350 in equipment to produce colloidal gold.
