Thorens TD 125 (1968–1975)
A turntable that bridged Thorens' Swiss and German eras, combining idler-drive mechanics with early electronic speed control.
Overview
The Thorens TD 125 is a turntable produced from 1968 to 1975, marking a transitional period as Thorens moved manufacturing from Switzerland to Germany. It succeeded the legendary TD 124 and served as the direct predecessor to the TD 160. Known for its robust build and hybrid drive system, the TD 125 was positioned as a high-end deck in its time and remains highly collectible today. Two main versions exist: the Mk I (1968–1972) and the Mk II (1972–1975),

| Original MSRP (Mk II with SME arm) | $399 |
Design
The TD 125 uses an idler-drive system paired with electronic speed control—a first for Thorens—improving on the mechanical precision of the TD 124 with greater speed stability. It features a heavier, larger drive assembly than its predecessor and was built with a focus on long-term durability and serviceability. The bearing system uses a long sleeve with highly polished surfaces and a single steel ball for thrust support, contributing to its low wow and flutter performance.
Context
Introduced in 1968, the TD 125 directly followed the TD 124 as Thorens transitioned production from Switzerland to Germany. Its development reflected Thorens’ effort to modernize their high-end line while maintaining mechanical excellence.
Market
The TD 125 is highly sought after, with units commanding strong prices on the used market—for example, one listing offered a TD 125 with original box for $1,250. A common failure point is capacitor degradation, particularly in the electronic speed control circuit. While service manuals and spare parts are available through enthusiast communities, some components like dust cover hinges are frequently missing or damaged.
