Additional information
The CJ Walker CJ 55 turntable is a notable model recognized for its effective engineering and performance characteristics. Below is a detailed technical description of its features.
Design and Construction
Material Composition: The CJ 55 features a plinth made primarily from wood, which helps in minimizing vibrations. The platter and sub-platter are constructed from Masonite, a dense material that contributes to a quieter operation by reducing noise transmission from the motor and bearing.
Suspension System: This turntable utilizes a three-point suspension system that allows the subchassis to float, effectively isolating it from external vibrations. This design is similar to other high-quality suspended decks, providing enhanced stability during playback.
Removable Arm Board: The CJ 55 includes a removable arm board, allowing users to customize their setup by accommodating various tonearms, including popular models like the SME.
Motor and Drive System
Motor Type: The CJ 55 is equipped with a 16-pole synchronous motor that operates at 60 Hz. This motor configuration is designed to provide stable speed and low noise levels during operation.
Belt Drive Mechanism: The turntable employs a belt drive system, which helps isolate motor noise from the platter. Users have reported that the best performance is achieved with specific belt types, such as flat belts measuring approximately 3/16" x 0.03".
Performance Features
Speed Control: The CJ 55 offers two speeds (33 RPM and 45 RPM), but users have noted issues with speed stability, often running slightly slow (around -3.2% off) due to factors such as motor pulley height and belt condition. Regular maintenance, including cleaning and lubrication of the motor bearings, is recommended to mitigate these issues.
Wow and Flutter: While specific measurements for wow and flutter are not widely documented, the design aims for low distortion and stable playback, which is typical for turntables of this class.
User Experience
The CJ Walker CJ 55 has garnered mixed reviews among users. While it is appreciated for its solid build quality and ability to accommodate various tonearms, some users have faced challenges with speed consistency. It is often considered an entry-level option compared to higher-end models like Linn or Ariston but still delivers respectable performance for vinyl enthusiasts.
