It’s been great fun following these suggested “traps.”
For a taste of reality, the Los Angeles City projectionist license test in the 1950s was in two parts, written and practical. If the examinee survived the written test, which included calculating lens focal lengths for various throws and screen sizes and electrical exercises based on Ohm’s Law, he was ushered into a real booth in City Hall and asked to thread up and run a short film while the examiner set as few “traps” of his own that began with feeding the carbon arc lamphouse with AC. If the examinee identified the problem, the examiner could then feed the lamphouse with dc with reversed polarity. If the examinee identified that problem, he was then expected to thread the ancient projector and equally elderly soundhead and then deal with no take-up reel belt (one was provided if asked for), the wrong focal length lens (the correct one was provided if asked for), and deal with other surprises including blown renewable-link fuses. It was rare for an examinee to pass on the first try, but the license was “earned” in every respect.
The Los Angeles County projectionist license test did not employ a booth, but examinees were required to make cement splices that could endure a pull-apart test and an examination for workmanship. “Workmanship?” Does that term even apply any more?

Evil alright - WD40 in the frigging xenon - wish we sold your site lamps !
I look after a site where a new operator felt he should be promoted, however the company took on an older guy with really solid experience. The young guy was pissed off to say the least, and slagged the older guy off no end. Then "things" started happening on the older guy's shifts - strangely on the first show of the day ALL screens would have a film break, only on the first show... The older guy would lace up and run all shows himself fine, but whenever the younger guy was on the night before shit would happen. Usually a film break in the middle of a reel in the middle of a featyure, and once timed so that all three screens broke at once. I rememver once the current on a rectifier was turned way up (110A for a 1k6) and the lamp and mirror blew - other times there would be "mysterious" sound faults, and the older guy would ring the younger guy to ask if he had any problems.. The younger guy would offer to come in and help, and within seconds of "fiddling" in the back of the rack the younger guy would have "saved the day" and became everyones hero. Finally the older guy had too much and resigned. The younger guy took over as "chief" and his first rule was not to clean the platter discs - apparently the film slides off ! (Thankfully the younger guy then decided he was an engineer and left the company, proclaiming that he could set up a CPxx by ear better than anyone with calibrated test gear could)..
Maybe he's rignt - an fed up with humping a scope, analyser, laptop and set of loops and cards acvourn
