I totally agree with Stephen. I apprenticed on the Gaumont-Kalee back in the mid 60's. (We had quite a number of them in the Odoen theatres here in Canada). They were extremely wll built and gave very little trouble, unless, as Stephen mentions, you forgot to change the aperture. They manufactured sound systems under the name DuoSonic. As an example of their design, the power supply filter, instead of consisting of a 470 uF capacitor following the rectifier tube, used five 100 uF capacitors in parallel, each with its own fuse. Should a capacitor short (a common problem in tube systems), the show was not lost. Instead, the fuse would blow, taking that capacitor out of the circuit. A very slight hum would result, and the technician could replace the capacitor the next morning. Like the Cinemeccanica, changing, or reversing the intermittent sprocket required only a screwdriver and about three minutes. Like the Simplex 35, they had an oil-bath design. Due to the lack parts availability, almost all of them have been replaced.
