For the 800 Eumig Seies....
Cleaning the Sound Head:
METHOD 1: (for a quick clean). The sound head is located right underneath the Bulb. It has a white cable coming out of it, which plugs into a receptacle on the chassis. For a real quick clean, take a can of air duster and blast air down into the Teflon film chute at the front of the sound head assembly. This will blow out any loose oxide particles in the sound head. This process is recommended after every couple of reels, to keep oxide from building up inside the head assembly.
METHOD 2: ( FOR A THOROUGH CLEAN, THIS PROCEDURE TAKES ABOUT 30 MINUTES, AND REQUIRES DISSASSEMBLY OF THE SOUND HEAD). 1. Set the control knob to the Forward position then pull off the black control knob at the side of the projector. Remove the lamp housing cover. 2. Pull off the volume control knob and the mixing control knob. 3. Undo the screw located between the volume control knob and the mixing knob, and pull the side panel forward and out to expose the inside of the projector. 4. Unplug the sound head, then undo the single screw which bolts the sound head to the chassis wall. 5. Remove the sound head. 6. Look at the sound head. There are a total of 6 screws in view. Do NOT touch the four innermost screws, they are used for the critical elevation and azimuth alignment of the sound head to the magnetic tracks on the film. Undo the 2 outer screws to remove only the MU-METAL magnetic shield, and the pressure pad assembly. You now have total access to the heads and pressure pads for a thorough cleaning with alcohol. Be very gentle in wiping the head areas. You may wish to de-magnetize the heads while you are at it, using a Radio Shack tape- head demagnetizing probe. Also polish the film channel and pressure pads with Pledge or Favor furniture polish. 7. After cleaning, reassemble the mu-metal shield and pressure pad assembly to the head, and tighten down the 2 outermost screws. 8. Align locating hole on the sound head with the pin in the chassis, and bolt back into place with the single screw. Plug the sound head back into the wall connector. 9. Reassemble the side panel, audio knobs, and Main control knob. Return the control knob to the OFF position
