so i typed up this long long post about this, then it got deleted, so this is going to be pretty simple. so at one of the theatres i work at, im going to be tearing all of the equipment and cables down to check, organize, and clean everything. i was wondering, when you send a fixture into a shop to get general maitnenance, what do they do? what do they check and everything? the insturments by the way are fresnels and shakespeares.
