Needle Turntable and Stylus Life

The turntable and the one consumable on it that wears out without telling you, led by a stylus life bar with the hours remaining and the percentage used both computed from the same pair. The replacement date is projected from a weekly average taken off twelve weeks of play, the deck and tonearm are drawn from computed svg primitives, and every maintenance job works out days since against a fixed reference date.
