Water coolers and air conditioning? Gee, thanks guys, I hadn't thought of that. Saves me from borrowing a lot of ice from the concession stand.
Back to digital problems, the old Simplex souhndhead manuals for the SH-1000 (four-star) soundheads (similar to the Five-Star, but built better), used to recommend putting the sound impeadance roller in the un-locked (thread) position overnight to prevent the occurance of a "flat spot on the roller which might cause a slight warble in the sound until this flat spot rolls itself out. (Sort of like nylon tires in cold weather).
Given the Dolby digital tracks suseptibility to "vertical jitter", I wonder if this practice should again be adopted. Here in Toronto, with the Union contract being what it is, projectionists are often told to go home before the last performance is completed, thus this task would be left to managers or ushers, some of whom leave a projector running all night with the lamphouse on.
A second item in the old Simplex manuals advocated putting an occassional drop of oil on the pin that locks the impeadance idler in place. This pin is located under the sound drum and is what catches the latch when you close the idler. The purpose of oiling it was to prevent the latteral guide roller from sricking in the wrong position due to friction on this pin.

My question is about the basement readers for cinemeccanica. I have a vic8 wich i will like to run 'digital'. By reading what you have posted earlyer it depends on wich projector you have. I could of cause buy the penthouse reader ( cat701 ) and get away from nearly all problems except one, that is when the upper reel feeds the film in to the reader it can go thight/slack (varios) is that a VERY big problem?Thats why i will like to no if the basement readers made by cinemeccanica (in my part of the world) are worth buying? I have a platter so i COULD of cause skip the upper reel for running digital and purchase a penthouse reader and be happy  So the main question is:
Are the basement readers for vic8 worth buying? do they run with out to many -F-'s? Another big issue here i will ONLY run film collector prints. They quit often are not all in the best condition. The cat701 will be best for that i think. A lot of question from me in one post, hopefully with out to many spelling mistakes, i am getting better at it all the time  Any help is very appreciated.
