Could static be the culprit?
When I first set up my Michell Orbe SE in my old house, the power supply would mysteriously switch from 33rpm to 45rpm and vice versa mid-play. There's a button on the power supply that you push to do so, and the light indicator would go from green to red to indicate that the speed has changed.
The Michell engineer figured out that it was due to static build-up after I walked across the room on carpet. So I touched the rack to dissipate static before I touch the turntable each time, and the problem went away.
Just a thought.
