I second the inclusion of "test films" in the list. Personally, I think that every theatre, particularly multiplexes (where the cost per screen is low), ought to have a full set of test films for picture and sound alignment. Test equipment would be nice, too, but the resourceful projectionist can usually find someone who will loan him, say, an oscilloscope for a day or two.
Every theatre ought to have a 2000' split reel and, if they are using ELRs, a 6000' Goldberg split reel. I once dealt with a feature that was shipped on cores, which got interesting because we only had a 1200' split reel in the theatre. I ended up attaching (with maskign tape) a 2000' 16mm reel to one side of it and using a handcrank rewind bench to slowly and carefully transfer the film to/from cores and Goldberg 2000' house reels. This was Not Fun.

I agree with Jim's choice of test film for the booth (provided they are used with a reasonable amount of thought).RP-40 is valuable for checking lens resolution, aperture alignment and travel-ghost (although for the latter, I prefer the B.O.F.T.G.T.K.). The Blind Old Fart's Travel-Ghost Test Kit consists of a loop of high-contrast black and white credits from an old trailer and a pair of 10 X 35 binoculars. The Buzz-track is great for determining whether that vacuum-cleaner sound in the background is an improperly printed D.T.S. track or a mis-aligned latteral guide assembly. Cat 69 T is essential for checking Dolby level to assure level matching for optimum noise reduction, however, don't be too quick to pick up that tweaker yet! This system was, presumably, perfectly set the last time it was aligned. Something has changed. It is probably not the solar cell, and Dolby pre-amps are quite stable. The change, therefore is likely in the sound-head. First, check for dirty optics, sagging exciter lamp filliament (correctable in most American soundheads), or tampering. Check these possiblities first. If using the old black-and-white Dolby C.N. 69, make sure that the right side of the loop is threaded and you are not trying to reach Dolby level with pink noise. P.S. It helps if you buy the technician a coffee or two.

The time I use my piece of BT-35 is when we get that 'vacuum cleaner' sound...I adjust the L.Guide and shut off the proj, and re thread. If it STAYS in alignment, OK. If it doesn't, the problem isn't the L. Guide roller. (I have to call NCS -- The new guy we got is pretty good.) BTW... If you get a 'SCRAPE....SCRAPE....SCRAPE' sound or a 'freight train' sound in the background..... I just recently discovered that you can visually see the bad soundtrack. It fades from black/purple to blue, repeatedly. I mentioned this because I USED to think it was something wrong with the proj.
