What is the best lubricants to use on Eumigs? I have one that works totally perfectly, and the speed is accuarate but there is a sort of "revving" sound when the machine warms up. This is roughly once per second.

Simon,
I think the reving sound you are hearing is a characteristic of the 800 series Eumig's. Both my 800 Eumig's seem to exhibit this, and its mainly noticeable when the machine is in the stop position and only the motor is running. So it seems to be a mechanical resonance or beating effect in the motor. I dont think it is a problem at all, just annoying.

My Eumig's revving sound is only present when the machine is running. With only the motor running, no such sound is heard.

I second Paul on this. The sound you mention is not aproblem.
But from time to time, it might be sensible to relube all of the warmgears and shutter/claw assembly with grease, even if Eumig claimed its projectors were maintenancefree and self-lubricating: I don't think this is to be ragarded still effective after so many years from production.

The reving sound we discussed here has no detrimental effect on picture or sound from my Eumig S926 stereo, but to be on the safe side, I think careful precise lubrication is needed. I have ordered Microlube, as shown on Wittner's site, but available on other sites here in the UK, such as model car supplies. (Microlube is from ZX1, whom I understand make USA space-center tested lubricants!) Microlube is a small amount of lubricant but with a precise applicator tube. I wonder if lubricant in the right places may make a difference to the reving sound? I think I counted about four of these "revs" in a second, but only when the mechanism is running.
