Maurice, Do NOT mess with the clip on the end of the flywheel. That clip is actually a form of leaf spring which loads up the teflon bearings on the flywheel to eliminate axial play in the flywheel assembly. Take that clip off and you are likely to get yourself into a whole heap of sound WOW problems. Leave well alone. To clean the flywheel and rubber roller you push downwards on the red button (below the flywheel), which tilts the rubber roller and gives some limited access for a long q-tip swab soaked in a little alcohol.
Tom, one problem that I have encountered on both my 926's is breakage of the leaf spring stack which indexes the positions of the main control knob. The projector still works fine, but now you have to visually set the knob to its appropriate clock positions, and can no longer rely on the feel of the indentations. Looking at my 938, it looks like Eumig were aware of this problem on the 926 (clearly they did not do any stress analysis on the leaf springs) and corrected it with a new design of spring. The other 926 problem was breakage of the indent mechanism for lifting up the rewind pulley at the top of the machine. Yes, the 926 seems to have some overly stressed parts, both metal and plastic (some of the plastic parts associated with the curved input guide are ridiculously thin and the pulleys are tiny), but the 938 has none of these component problems and is a totally different design of input film path. But I agree Tom that the 900 Eumigs do not have the tank-like construction of the Elmo GS1200.

Eumig were always ahead of the curve in projector design. First projector with low voltage halogen lighting, first low cost 8mm sound projector, first (and only) projectors with vertical lens shift, first projector with microprocessor controlled recording/playback functions etc etc. Most other manufacturers seemed to follow Eumig's lead. It is interesting to speculate where Eumig would have taken us in super 8mm had they not been bankrupted by their association with Polaroid, and had video not come along and decimated the market for cine. I think Dolby stereo optical sound projectors would have been one of the next steps for them, as well as a 1200ft Stereo mag/ stereo optical projector with xenon or HTI lighting.

I dealt with the gentleman who ran Photo & Electronic Service fairly regularly throughout the 80's. I bought at seperate times two S926's and an S938 all new, as well as various parts and repairs. He was also nice enough to give me a parts diagram for my own repairs. And he believed the crowning Eumig achievement was the S824D Sonomatic, which he used personally!
Then, one day, I phoned him and a lady just said "Hello." So I asked to speak to the projector repair gentleman. And she said in a rather frantic and foreign sounding tone, "No! Not here! No more parts! Sorry, no more!" And that was my last contact with them. Oh, and I called several more times to make sure, unintentionally causing a little upset. Sad.
Well thanks for the Cambridge Camera tip! That would be too good to be true if we could get more soundheads!

Hi Mike,
Yes the 824 Sonomatic is a sweet little projector. I have an 820 Sonomatic and every time I pick it up I end up admiring its brilliant design. These are such compact and rugged little machines, and yet built almost totally of metal, as the best projectors are. Eumig got it so right with the 800 series, great little work horses for the average home projectionist. I believe that the 900 series were designed by a different team in Vienna, and you can really see the total change in design philosophy, particularly the move to heavy use of plastic moldings. I have often wondered why Eumig did not keep the basic superb 800 series mechanical design, and just add to the bottom of it an outboard stereo recording/mixing console, similar to the 926/938/940, plus some extension of the reel arms for 800ft capacity, and also with the optical sound head of the 800 M/0. Now that would have been some projector!

Hi Graham,
Unfortunately there is no 'quick fix' for the 926 control knob indent mechanism. The problem is that the leaf spring stack is severely overstressed and the top leaf spring, which engages the plastic cam on the back of the control knob, breaks off due to stress fatigue. This is clearly a design mistake on Eumig's part, and they made a design change in this area on the later 938 and 940.
Fortunately, the operation of the 926 is not affected at all by this, as long as you visually line up the white mark on the knob with the arrows on the cover.
