I've recently purchased a dual format Chinon.
A new belt, and it works, mostly. Sometimes the gate seems to not work properly. It will show one film fine, then another will be very jumpy, or not gate at all.
I'm guessing it just needs a clean / lubricate, but anyone any advice? or even better a service manual for a chinon 8811? Even a user manual would be a help.
I do have separate standard 8 and super 8 projectors, but I'l be wotsited if I can find the mains leads!
