Default Re: Ampro New Educational - motor woes, issues and solutions

Thanks for your thoughts David, some things to think about. The only problem with any modification on these projectors is the tight space inside it, everything was designed to be as compact as possible and it can make repairs difficult.

I do wonder if I can make some replacement point contacts up and replace those currently fitted, another option is to try and find the Ampro part number for the points so I can see if any old stock exists anywhere. A third option is to file them down more which will probably reduce the thickness of the points by half.

It makes me wonder how many hours this projector has done, from appearance it looks to be relatively low hours but I suppose with proper care these machines can look so even with thousands of hours use.
