Field power should remain the same unless that can confuze things. Thats a separate 15 volt supply, not switched, although it could be plugged into the power strip that controls all the motor power. Should I? I think the boxes line cord will reach. Maybe, its a scrap. No bets. :) I think that covers it but dbl-check me. I'd also point out to Peter that the scale of the drawings in the 7i76 manual needs to be expanded. The only text on page 52 thats readable is the Mesa, all the other lines are so thin they're lost in a 1200x1200 printout. It all looks like its scaled for a readers digest sized page, and gets lost on an 8.5x11 page. I can scale it up, but forgot to this time.
