Re: Bell and Howell TQII 1652 16mm projector
Thank you Lucien,
I had to double check the position of D2, but sure enough it's there. If the tacho itself produces something of the order of 30V peak to peak, it seems really weird to short one cycle out. Mind you, I don't really know what that component is for sure. There's just an ordinary diode symbol in the PCB screen printing a that location.
