Update: Still working i.e. no more dragged stylus. It still lifts at an angle, since my leaf switch is detecting the solenoid return NOT the oil-damped lifting of the arm. 

It occurred to me that if the leaf switch fails (stays open when the solenoid returns) I would be in a MAJOR pickle, since the sled won't return... imagine trying to remove an LP with the sled stuck in the middle, how would you lift it over the platter pin with the arm in the way?

So, I soldered a very small tilt switch - on the PCB in the place shown in the photo above - mounted at a 10 degree tilt; if the leaf switch fails = sled doesn't return, I just have to tilt the whole turntable up about 10 degrees and the sled will return as usual. (I hope!)
