Hi folks!
If I may ask for your insight again re: this wonderful projector...
Just noticed that a hum has started when playing sound films, and wondering what folks might recommend to clear-up the problem? Wasn't happening a few months back...
Cheers, and thanks!
-Anthony

Anthony,
Hum was the plague of the Eumig 800 series. It can be reduced by adjusting the position of the little hum-bucking coil situated right underneath the sound head. Remove the side cover and set your projector to play with sound, but with no film, and turn the volume control way up. Carefully move the hum bucking coil around to minimize the audible hum level.
Another way is to feed the output of the 807 thru a 10 band graphic equalizer and then to an external amplifier, and notch the equalizers filter settings at 120 hz.
