Question on that -- if the lights are blinking at the wrong frequency and the tape motor is thus
running a bit fast or slow, why wouldn't that register on a calibrated strobe wheel? Won't lights
that aren't 60hz make the strobe pattern move just the same as wheel speed that's not right? Sorry
if it's a dumb question!
