Hehe, I worked at one theatre where they used AMX-192 for everything but still had those rheostat dimmers. THEY WERE HUGE!! We called them "Frankenstein Dimmers". The dimmers were about half a meter tall and the handles you used to dim were above a meter long. Obviously they weren't hooked up, but the thought of running a show with those things was just funny to me! I can't imagine how HOT it would have gotten in that small lighting booth with those dimmers being used. TTYL -- http://www.piclist.com hint: The PICList is archived three different ways.
