Pradovit RT-s Projector

Online I bought a Pradovit RT-s Projector and it does not work as designed and jams slides. Is there someone in UK who can repair it? The slide channels are not parallel. I also have a Kodak Ektapro with the same problem. Both projectors seem to dislike slides with cardboard mounts and prefer plastic mounts.

Cardboard mounts have always been a problem in my experience. I always replaced them.

You could try Newto Ellis in Liverpool (https://www.newtonellis.com) who still list slide projectors as items that they repair. I'm tend to favour jaapv's suggestion though - try remounting in plastic mounts which may solve the problem.

I had a Pradovit RT many years ago - great, solid and reliable projector when I had it.

I did prefer the plastic and glass ones, even if dust and Newton rings could be problematic   They kept the slide nice and flat.

I had an RT-s for about twenty years.  Fabulous machine.

A 'stupid' question:  are you using 80-slide trays?  (The 140-trays are useless, in my experience, in terms of jamming.)

Yes, I have one 80 tray (right word?) thanks for your reply

Drop shaft projectors, such as those were built by Kodak, Leica and Simda, have always been very suitable for all types of slide frames, including cardboard slides.
But for cardboard slides, the projector must be aligned exactly on a flat surface and must not be tilted at an angle to adapt to the screen.
