Development of a Split-Plinth Rega-based Turntable     

Conversion of a venerable Rega Planar3 deck

<< RevolverMod1      < Other Pages >       Gyro-inspired Rebel >>

This is a unique design turntable constructed using Rega parts for all electronics and running gear. The primary feature of this deck is the dual plinth design which ensures total isolation of the motor sub-chassis from the platter/tonarm mounting plinth. Components and construction techniques include:
  • New-style P3 Motor
  • 12.5mm Acrylic Platter
  • RB-301/Mitchel Tonearm
    		•
  • MDF Lower Plinth
  • Dupont Corian© Upper Plinth
  • Dynamic Cone suspension

    • A summary of the construction process for this turntable project is illustrated below:
