Rectifier transformer terminal markings.

Won't you get an interesting smoke effect if you run older motors on A.C.? DCC of course uses AC so it does get confusing, it has a flattened off wave form or something, also used in controlling the speed of diesel electric ships and that does get technical. I have bought very little in the...
