If you go to yahoo groups, there is a group called cg_exchange, under the file section there a few different blue prints you can build one under. Youll want to build the one using the mot(microwave transformer). Dont use the (nst) neon sign transformer. One word of caution, as you said before, it takes a lot more power to create Colloidal Gold than Colloidal Silver , and the electricity could kill, so be careful.
