the light from the lens goes through a beam splitting prism and three color filters. each filtered image goes into a vidicon tube. notice all the adjustment screws? yeah what a pain to align.
i'm consulting an expert now. he once told me how he had to spend hours adjusting similar cameras, so now i get to experience that too, only without any time pressure.
ok here's an electrical puzzle. this center-sprung zoom button has 4 terminals and must have potentiometers inside, but how are they connected? I made a table of resistances for all combinations of pins with the control in different positions. can you figure it out?
I can't open the potentiometer without damaging it since it's glued shut. this is really bothering me now lol
