Thorens TD-126 Mk III
A Swiss transcription deck that ran three speeds, took a 78 stylus seriously, and cost £280 with arm, base, and cover included.
Overview
The TD-126 Mk III was Thorens' semi-professional transcription turntable. The spec sheet reads like a deck built for the transfer bench as much as the listening room. It ran three speeds - 33⅓, 45, and 78 rpm - which is what separates a working transcription machine from a domestic two-speed. The drive was a single-step belt system with a servo-controlled DC motor, and the platter was a 12-inch unit. Thorens quoted wow and flutter at 0.04% and rumble at 51 dB unweighted, 72 dB DIN weighted. Two numbers, and the second one is the flattering one.
The arm was the TP16 Mk III, an Isotrack design. Thorens listed its lateral tracking error at 0.18°/cm radius, arm length at 230mm, and friction at 0.15mN in both planes. Those are figures for a low-friction gimbal arm, not a mass-market afterthought. Bias compensation was magnetic, working without friction. The TP16 Mk III was also sold on its own at £35, so the arm was a component in its own right, not a permanent fixture.
Power was specified at 117/220V, 50/60Hz. That dual-voltage arrangement let the same deck ship into European and North American markets. The price was £280 including arm, base, and cover, which put the complete package in the serious amateur and small-studio bracket rather than the audiophile stratosphere.
Period coverage places the deck in the late-1970s British market. HiFI-Stereo (September 1979, p.23) ran a Thorens advertisement announcing a five-year guarantee across the turntable range, with the Isotrack tonearms explicitly included in the coverage. The only cost to the owner was shipping to a Thorens technical service center. The guarantee extended to the arm, which is the part most likely to be abused by a careless cue.
Audio (October 1978, p.100) listed the TD-126 Mk III among its turntable survey entries, alongside the Setton TS-11 and Sony PS-X6, with the letter-code speed table confirming the three-speed (33, 45, 78) configuration. The deck was being positioned in the same conversation as the direct-drive Japanese competition of the moment — a belt-drive Swiss transcription machine holding its own against quartz-locked direct-drive designs.
Collectors chasing a TD-126 should verify the arm is the TP16 Mk III and that the base and cover are present. The £280 package price was for the complete set, and buying the pieces separately is rarely cheaper.
