Re: Bell and Howell TQII 1652 16mm projector
I realise it is human nature to always suspect that the part you can't get is the faulty one. But in this case, I assume you've checked the few components around the module, and we know the tachogenerator is producing a signal. So it pretty much has to be that module.
In which case, I don't think you have anything to lose by trying to get into it.
