Specifications in detail

Reel Capacity

Reel arms accommodate 400 ft reels. Both reel arms fold downward for storage.

Threading

Automatic threading from reel to reel; the device feeds the film into position and forms the loops to the correct length -- film continues threading underneath and to the rear of the projector onto the take-up reel; Manual threading and unloading possible, if desired. Lens assembly pivots outward for cleaning of gate and unloading of film.

Power

Two versions: 1) 50 cycle 110-240v AC power; 2) 60 cycle 110-125v AC power.

Lamp

12 volt, 75 watt lamp. Earlier models used the 13730C04 RT44 bulb which is now obsolete with no modern equivalent. Modern replacement for later models: EFN 12V/75W Halogen lamp.

Lens

Interchangeable lenses; Originally supplied with a choice of four lenses: Bolex Hi-Fi f/1.3 lenses of 15, 20 or 20mm focal length or with the Bolex Hi-Fi 14-25mm f/1.3 zoom lens. An Isco Vario Kiptagon 16.5-30mm f/1.3 lens was usually equipped on later models.

Variable Speed

18 and 5 frames per second; 18fps reverse projection; Rapid motor rewind. Forward or reverse motion with lamp switched off at 18fps. Speed dial allows switching directly to reverse projection from forward projection.

Other Features

Framing knob adjusts the claw for vertical alignment in the gate; Front leg for height adjustment and rear legs for leveling; Variable shutter automatically changes from three to nine blades when projection drops to 5fps; Catathermic filter preserves the film from excessive heating; A table lamp can be attached which switches off when the projector is running and relights again when stopped.
