Went to the flea mkt. and got 8 little black plugins that convert AC into 9 volt DC with output of .2 to .5 amp.These are typically used for small electronics such as calculator or radio
Has anyone else connected these in series? I plan to try them at 27 to 72 volts and see what happens. Many jewelers work with bezel wire which is .99999 to my understanding. A jeweler's supply house would be even better. Dan
