Ampro 16mm projector

[LangISback]

I just bought a 16mm Ampro projector, very old but seem to work just fine, the mechanism runs smooth and the lamp is very bright.

 

I ran on it a negative I made to test my 16mm camera, which has the rank prep white leader.

 

The problem was this:

The white leader ran just fine (about 20 secs), it is single perf.

But, when the double perf. negative entered the sprockets, the projector mechanism started to make a loud noise and the negative came out with big damage on the sprocket holes. At some point the negative even broke.

 

I want to know if the problem is with my projector or if I can't play negatives on 16mm projectors or if there is some issue with the a-wind b-wind thing.

 

Any help would be much apreciated.

 

regards!
