Original poster: "Harold Weiss" <hweiss-at-new.rr-dot-com> Hi All, In a theatre I came across some old Davis dimmers. They are linear instead of rotory. They have a 120V 50A coil and 6 20A faders, that in combination can draw 50 amps. The dimmer weighs in at around 60 lbs. (guesstimate) The theatre has three of these units, and is willing to part with them at low cost. Anyone interested? David E Weiss
