A Reba Arm Upgrade on the Revolver Redwoood Turntable
Revolver turntables gained some popularity as a budget audiofile turntable in the 1980s and 90s. Their design include a 'split plinth' and outboard belt drive now used in several highly acclaimed mid-range turntables such as Music Hall 7.1. The primary weakness of the Revolver however, is it's relatively low cost tonearm with degrading microphonic affects. This web page describes how the original low cost Linn-mount tonearm can be upgraded with the excellent Rega RB301 style arm for vastly improved sound.
