I think I can buy these for reasonable costs. Gonna try a repair!
Here's some more pics from inside the box.
All the electronics look fine, all the bearings and pulleys and the oscillating mechanism are fine. Curious I don't have the rectifier circuit board that the review I posted earlier showed... Is that what the square thinger the brown and blue wires connect into between the switch and motor?
I'll let you know whenparts show up if the rotor and brushes fixes it. Feeling confident.
