Mission 774 (original)
Rigid Low Mass Stereo Tonearm
The original Mission 774 tonearm was designed by John Bicht and incorporated fluid damping and a detachable alloy arm wand.
The arm is designed to direct couple the cartridge assembly to the turntable mass.
This is essential in that if the tonearm suffers free play, it will inevitably set itself in motion independent of record modulations thereby adding to and subtracting from information retrieved by the stylus tip.
The secret of the Mission 774 is its unique rigid bearing design, elimination of conventional 'flapping' headshell and other resonating parts, total structural integrity, low effective mass and minimal pivot friction.
The arm employs silicone viscous damping and three different damping paddles are supplied with the 774 to optimize the performance of different cartridges of varying compliance.
Effective length: 229mm
Effective mass: <5.5g (depending on counterweight)
Friction: <15mg (horizontal and vertical)
Downforce error: <0.2%
Fundamental resonance: 5 to 18Hz (depending on cartridge)
Cartridge mass: 2 to 10g
Connections: 1200mm cable
Armtube / headshell assembly: interchangeable
Hydraulic damping: viscous fluid
Cable capacitance: 125pf (per channel)
Adjustments: height, tilt, overhang and bias
Optional extras: arm tubes and counterweight
Arguably one of the finest low mass tonearms; the Mission 774 is distinguished by its dry and controlled neutrality; upper midband was slightly hard; offered a fine transient performance - £157 HiFi Choice 1983
