Adam,

Actually my Luxtrol looks almost identical to the 1256D's that you
got from me, externally. I'm at work now so I can't snap any pics to
send to hotstreamer-dot-com. Maybe if I can get out my digicam tomorrow,
I can snap a pic of it and put it on hotstreamer. The only difference
is the stick-on label that reads "Luxtrol" instead of Powerstat. Of
course it is taper wound like yours and has no taps like David Weiss
mentioned.
