on my gemini xl-500 II's i cant get the little dot to not move at zero
in fact i cant get them to not move at all!

there 99.9 percent good ecept at every rotation the moove a tinnny bit
is it maybe cuz the platter is crooked?

Oh, i had the same problem. I fixed that by taking a screw driver and adjusting the pitch adjustment. When at 0 your strobe points shouldnt move at all, if your points are moving when you are 0, take a small screw driver and adjust the screw in the little hole above the pitch adj. knob. Put the screwdriver in lightly, and very nimbly turn it. It takes about 5 minutes to do on each, but its definitely worth it.
