Description
The Philips GA312 is a sprung chassis, belt-driven turntable with electronic speed control.
Stylus force on the GA312 is set by means of the slide weight on the pick-up arm after this is balanced with the counterweight.
The player is equipped with an adjustable anti-skate which applies a pre-set force to the arm counteracting this phenomenon.
The motor speed is continuously controlled and kept constant by solid state circuits in combination with a tacho-generator which is directly coupled to the motor shaft.
The platter and the pick-up arm are mounted on a sub-chassis, which is damped, spring suspended from the rigidly mounted main chassis, absorbing mechanical shocks and external vibrations.
