Another Pacific Stereo story. We had several sound rooms and numerous systems setup around the store. Since the store was hands-on, it wasn't uncommon for customers to fiddle with adjustments on demo gear.

I was dusting in one of the sound rooms one day and noticed a turntable was still turning with the tonearm in the center groove. It wasn't connected to an active power amp so it was completely silent and had been spinning for an undetermined amount of time in the center groove.

I turned off the spinning platter, lifted the tonearm, and tried to lift the LP off the platter. To my surprise, the label stayed on the platter while the remainder of the LP was lifted off. The needle had worn through the vinyl completely! Apparently someone had mis-adjusted the tracking force and the excessive needle down force machined its way through the spinning record.
