Most of us have a shirt pocket music player that can hold 5000 record albums (or one telephone message from your mother-in-law) but there is still something elegant and satisfying about listening to vinyl at home. I use MSO2 grease on the platter sleeve bearing, and lubriplate (affectionately called "baby goo" in sound shops.) for everything else. The only service items are cleaning and lubrication. There is a lot of what I call "monkey motion" to change records automatically, but no serious collector allows his vinyl standing still to drop 75mm onto a rotating record below. The tone arm can track as low as half a gram, and has adjustable anti-skating magnets. When they do, the record will have perfect pitch. There is a speed adjust knob you turn until the printed lines stand still. This creates a strobe effect in the printed lines. Find many great new & used options and get the best deals for Vintage 70s Garrard Zero 100 Turntable for Parts or Repair. The lamp turns on and off at the line frequency. In front of the platter is a window with a mirror allowing one to see the bottom of the platter. The table is driven by a belt and there is a two step shaft on the motor to make the speed change between 33 and 45 rpm. As the mains frequency is stable in many parts of the world, this system was perfect for 1970's equipment. The frequency of the mains controls the final speed of the motor. The motor is a synchronous type, meaning the speed of the motor is unaffected by changes in mains voltage.
A 1Khz tone ET (Electrical Transcription is a 1940's term for a test recording.) plays perfectly in phase with a Zero 100.
The pantograph arm pivots the cartridge holder to eliminate phase errors unavoidable on conventional tone arms.
