I'm voting on a bad motor on Steve's case.John, yes they still use variacs...though the 8000 series rewind tables use a larger variac than the 7000 series. Steve ------------------ "Old projectionists never die, they just changeover!"

I get about 9 ohms on all opposing commutator segments, suggesting it's not shorted, which is strange since the process of elimination was strongly suggesting that. But the commutator was extremely worn under the commutator, like maybe a third of a mm. I'm trying to turn it down. The other clue was that the motor was harder to turn than it should be, despite nice, easily turning ball bearings. I was able to get it to run last night without overheating with it held together by its own friction (leaving out the long bolts) so I may be on to something. A replacement motor, while costly, is not as bad is one might fear, given the price of the table, so when I get bored with this "project" (a time rapidly approaching) I'm just going to give up and get order one.
