A BIG WARM WELCOME to our forum Ugo Grassi.
Thank you very for your very informative link regarding the Elmo GS 1200 projector.
We look forward to more of your posts.

Welcome Ugo. Nice to see you here. I wonder if my GS is safe? Nr. Parsons, do you remember if you checked these things on my machine? What would it cost to replace/modify one? Would the same apply to the GS-800? I got one of those too

Vidar ... I have been thinking the same about my GS 800 too.

Welcome Ugo and thanks for your comments.
Yes Vidar I did the mods on your projector, I would not worry too much about the GS800 it has a film path like the ST1200HD so is not so prone to problems, but it’s always worth checking the head pressers and the lower sprocket guide for wear, and make sure the pressure of the head holder rubber roller is not too strong, you could always send it to me some time to check, but I would not panic about it.

Great to hear, Bill. Thanks. BTW the Pinocchio Comes to Life ran much better, so I need to treat some more films that is unstable. Hope Iwwon't ruin any :-)

Ohhh A topic in my honor. Thank you my friends, I'm blushing...
thanks thanks...
:-)))

A late welcome from me also Ugo. It's really fantastic to have you here!

It goes without saying, Welcome my Italian namesake, and how he is going to convert me, welcome Ugo.
