ADC model 85
Vintage Pickup System
Consisting of the ADC model 40 gimbal-bearing tonearm, fitted with the ADC-1 moving magnet cartridge.
The Pritchard pickup system consists of the superb ADC-1 cartridge combined with an entirely new tonearm especially designed to provide the finest possible pickup performance.
The arm/cartridge is balanced in all planes making it very insensitive to external shock.
No levelling of the turntable is required; in fact perfect tracking may be obtained with the turntable tilted as much as 30 degrees to the horizontal.
The geometry of the arm is arranged to give minimum tracking distortion and not minimum tracking error - the reasoning behind this is based on the fact that a given tracking error in the inner record grooves produces more distortion than the same degree of tracking error in the outer grooves.
Arm length: 10 5/8" overall
Pivot to stylus tip: 9"
Rear overhang: 1 3/4"
Fundamental resonance: 6 cycles/sec
System tracks at 3/4g
