Hello every one. i just purchased one of these on e bay very cheap(£39} and agree with Paul regarding the sound quality,its the best ive experienced on super 8 by some margin.
However,the down side is that a lot of film ive run on this has a slight judder ,some prints more than others. By judder, i mean an unsteady picture,very slight ,but enough to spoil things.
Does anyone have a similar experience with the 900 series eumigs,or is this not going to be the bargain i thought!

Thanks David.

Hi David,
When I first got my S938 (off ebay) I had a similar problem. I found out it was due to the gate edge guide being slightly out of position, so that the claw was not perfectly centered on the sprocket holes. Remove the cover and open the gate with the little red clamp. You will see the fixed edge guide as the light grey plate , held in place by 2 bolts. If you loosed those bolts slightly you can adjust the position of the fixed edge guide to center the sprocket holes on the claw. This is a trial and error type of adjustment which should be done while running some old reel of film thru the projector and looking on the screen to make sure the picture is not tilted in the gate due to not getting the side plate exactly vertical. Generally speaking the claw will sound the most quiet when you have perfect claw centering. If you do this, and assuming of course that your film prints are reasonably lubricated, I feel sure your problem will totally disappear, it did for me. Give it a try, it's a pretty easy adjustment to do.

David,

I've had a few of these machines over the years, and I've had this problem a couple of times, it can be caused by cam wear, which makes the claw to pull the film through slightly erraticly, and may be noticed more on thicker film stocks like acetate. Try Paul's suggestion it may be just that, but if it doesn't solve the problem, then contact me and I'll give you a number for my repairer who knows Eumigs backwards.
