I think the Eumig S8xx machines are about your best choice for dual-8 machines with sound, with the sound itself being of high quality at that. 12V/100W EFP bulbs are cheap and easy to get... the only thing to watch out for (from what I've read around here) is the rubber wheel drive which may wear out over time and slip, but a good cleaning should take care of that (there is no belt, actually). These Eumigs come with good 1:1.3 zoom lenses... the "Lux" models have a bright 1.2 lens for those big pictures.
But 275 pounds? Rip-off, if you ask me
... OK, "rip-off" may be a bit harsh but at that price, I would expect a MINT-CONDITION, PERFECTLY WORKING model (...preferably a Sonomatic S824D Lux with twin-track sound :grin: ) with everything adjusted and replaced as necessary. For your typical used/working eBay unit, spend no more than 100 pounds...

Hi Rob,
Sorry I haven't responded earlier, but I have been away on business.
Can't add to what's already been said. It's a super little machine. The thing about these over the earlier Eumig dual gauge machines, is that you change the gate assembly and the sprockets to suit either Super 8 or Standard 8, rather than the old compromise of not doing so, with the (quite often, but not always) result of damaged film eventually.
You won't go wrong with a good condition 810D.
ENJOY!
Best,
Dave.

Valves and celluloid - a great combination! Early technology rules OK!

It is true that the grease in all projectors will get hard with time, and the self-lubricating bearings (ball-shaped brass-coloured, in metal cages) get passed their sell-by date. The practical solution for metal surfaces is to apply a LITTLE thin oil to thin the grease. I use Aeroshell 500 turbine oil, but any thin mineral oil will do. AVOID getting this on any plastic items: in a year or so they will embrittle and probably fall apart. Apply the oil, then run the projector for a while to get it to penetrate. For plastic surfaces, wipe off as much of the old grease as possible and replace with a grease intended for plastic surfaces (sold for video and dvd players).
The speed range of the Eumig 8xx is set by a large, shiny-metal screw just above the shaft that carries the two rubber-faced drive disks. This runs through a slot in black metal plate through which the 50/60 Hz switch passes. It clamps a shiny-metal bar through another slot. The further down this bar is, the faster the projector will run. Usual top speed is in the range 27.5 to 28 fps.
Adjustment of speed requires the use of a suitable meter: either a true r.p.m. indicator (measures the interval between pulses from the sensor) or a digital frequency meter (measures the number of pulses in a given time). The adjustment is very delicate; speed is extremely difficult to set by ear alone. I would not recommend attempting this adjustment unless you have the correct equipment and tools, and are used to using them.
Measure the speed with the projector running forward, with the lamp on, and with the take-up spool spigot clamped stationery to simulate a film load.
Examination of the metal bar below the clamping screw shows that there is a small hole in it below the slot. Once the speed-measurement equipment has been set up, and with the projector UNPLUGGED, set the speed control lever into a mid position. Insert a suitable instrument screwdriver in this small hole and hold it in place. Then, with a thin, but broad screwdriver, slacken off the adjustment screw no more than a half turn. This should allow the slotted bar to be moved UP slightly. (Movement of this bar about 2 mm covers the entire range of speed between about 23 and 28 fps, so only a slight movement should be made between speed measurements.) Now, tighten the adjustment screw, set the speed control lever to 24 fps and measure the speed. Repeat this adjustment until the required speed is attained.
Finally, check that both the 24 fps and 18 fps speeds remain correct. It is a good idea to check this in the 60 Hz (or 50 Hz if you a running on 60 Hz) position of the switch, checking that the speed corresponds to the ratio of the frequencies.
These instructions are based on my examples of Eumig 8xx machines. Euming were fond of making minor changes during production, so check your machine before starting.
I have never has sound recording problems with any 8xx machine. Then, I clean the heads and adjacent guides thoroughly and regularly.
