Original poster: "Loudner, Godfrey by way of Terry Fritz <twftesla-at-qwest-dot-net>" <gloudner-at-SINTE.EDU> Hi All Further comment about the photocopier transformers at http://personal.atl.bellsouth-dot-net/atl/a/j/ajones18/index.html . I contacted the owner of the site. Big Al got the transformers from H&R. Al does not use the third winding as it decreases the streamer length. Godfrey Loudner
