Replacing ETC Sensor dimmers with those from Applied Electronics? Not sure I see the wisdom in that scenario.
I meant buy a whole new rack, with some dimmers, and some distro circuits. Something like the photo, but configured the way the OP needs it. RACK SYSTEMS | *Applied Electronics Sell one of the old dimmer racks to recoup some of the expense. I don't know if ETC makes them but it wouldn't surprise me if they did. I didn't mean to imply that one should take parts from Applied and try to jam them into an ETC product.
