So last weekend I had the pleasure of going on my first touring show, Beatlemania Now. I was traveling with the sound company and learned tremendously, and actually applied some knowledge I learned here on CB . Anyway, my rant. We had 2 one off shows and the LD used the house lighting system both shows. Second house we did lighting rig was nice, except their older Colortran[I think?] Dimmer rack kept overheating . The TD there was clueless as to why it was happening, but midway through the show happened to tell us that this is new and recent problem, one that occurred to him the previous week! All and all, the show went on, but with half the rig cutting in and out as it heated up and cooled down. Is there anything I could have done to help the rack cool? Heck, I was thinking point a big fan towards it. Cheers and thank!
