About Thorens
FOUNDED : 1883
LOCATION : Head Office: Basel, Switzerland
MANUFACTURING : Goppingen and Iffezheim, Germany

For the past 100 years, Thorens has been one of the leading turntable manufacturers in the world. Very well known masterpieces with worldwide recognition have been produced by Thorens in the past. All of them with legendary reliability. Thorens is quality made in Germany for decades.

1883 Trade registration of the family-business of Hermann Thorens, established in St.-Croix / Switzerland, with the purpose of manufacturing musical boxes and movements.

1903 Manufacturing of Thorens' first Edison-type phonograph.

1906 Change-over to the manufacturing of horn-gramophones for shellac records.

1913-1964 Manufacturing of cigarette lighters.

1914-1952 Manufacturing of harmonicas (except for the time from 1921-1938)

1927 Conversion of the family business to a joint-stock company (AG)

1928 Development of the first electric motor (direct drive) for gramophones.

1929 Development of the first electric phono pick-up (employing a magnet principle).

1933 Manufacturing of wireless appliances, partly in cooperation with the Strassfurt-Imperial Company of Germany.

1940-1950 Production of professional disc-cutting lathes and phono pick-up cartridges.

1943 Production of the first record changer.

1954-1960 Production of the mechanical razor "Thorens Riviera".

1957 Introduction of the TD124 Hi-Fi record player. It came without tonearm but with arm board during this first year. Destined to become a classic, the success of this player had an enormous effect at Thorens, shaping the future direction for the company into that of a worldwide manufacturer of high quality stereo record players.

1958-1961 Introduction of the models TD184, TD134 with BL104 tonearm, the TD135 and the BTD-12S tonearm. These turntable models were simpler and less expensive offerings designed to fill out price points within the product line. The BTD-12S tonearm was well received at its introduction and was the company's top tonearm offering until it was superceded by the TP14 in 1966.

1962 Introduction of the unique TD224 HI-Fi record changer. Based on the TD124 but with smaller spindle bearing and shaft, additional gears, pulleys and levers, this 'record changer' stored it's stack of 8 records away from the player so that only one LP rested on the platter at any one time. An arm would pluck the record off the platter, then transport it to the side position, pick a new record from the top stack and place this record on the platter. This is quite unlike the traditional record changer that stacks one LP disc upon the next until you have a stack of 5 or six and spins the whole lot. As that stack of records on the platter rises, so changes the vertical tracking angle and correct arm cartridge alignment is lost. This complexity of changer operation, while extreme, ensured that the all important vertical tracking angle on this Thorens remained unchanged in play. The introduction of the TD121. A TD124 without strobe speed control. Marketed as a 'slightly' less expensive but high quality table. The introduction of the TD111.

1963 The Thorens company merges with Paillard SA, St.-Croix / Switzerland. Paillard SA manufactured Bolex cameras and Hermes typewriters at the time. This merger would last three years. Legal requirements and differing goals between upper management of the Paillard Group and Thorens resulted in a loss of cooperation between the two groups.

1965 Introduction of the TD150 with TP13 tonearm. This player featured a new 3 point suspended subchassis that carries both platter, bearing and arm. Fixed to the main chassis is a 16 pole, 2-phase synchronous AC motor. A two- piece 7 pound balanced platter system exists with the inner platter being driven by way of an elastic belt. Platter material is die cast zinc alloy. Platter bearing is a hardened stainless steel shaft of 10mm diameter with a captive ball bearing tip and running in sintered bronze bushings. The ball tip carries the vertical load from the platter. This new suspended layout presents a significant step forward in efforts to reduce rumble noise.

1966 Effective July 1st, 1966, the Swiss Thorens-Franz AG took over the entire business concerning Thorens record players and together with EMT Wilhelm Franz of Germany, they established a new business for research, development and manufacturing in Lahr / Germany, located in the foothills of the Black Forest.

Revision of the TD124 into TD124 II with TP-14 tonearm. Changes from the TD124 include change in paint color from cream white to medium-grey. The iron platter of the TD124 is changed to heavy aluminum (non-magnetic). Minor changes in the controls. Also revised was the TD135, now TD135 II.

1968 Introduction of the TD125 electronically-controlled (Wien Bridge Oscillator) turntable equipped with the TP25 tonearm. This table replaces the TD124 II as the flagship of the product line. The TD125, like the TD150, is belt driven and suspended via a 3 point suspension and like it's little brother, the TD150, it too is a "purists" model with all manual controls.

Early production units also share the same platters and bearing shaft with the TD150. Early models will be found with the captive ball on the spindle shaft tip. Later production models replaced this with a solid steel conical shaped tip to carry the vertical thrust load. The bearing housing on the early models differed from later production models. Early model platter bearings were housed in a large cast aluminum housing featuring a 3 bolt hole pattern for attachment to the subchassis plate. Later production bearings were of the press-in variety with a much slimmer machined steel housing.

Unlike the TD150, this model features a much more substantial and solid construction throughout. The motor function offered 3 speeds: 16, 33-1/3 and 45. This table was also offered in an optional "LB" edition. The "TD125 LB" featured a longer cabinet and armboard to accommodate longer 12 inch tonearms. For more info on the various options offered with the original TD125 see this link.

1969 Introduction of the TD150 Mk II with new tonearm TP13A. Upgrades to the tonearm include fine-adjustment of tracking force and 'weight on string' compensation of anti-skating force. The previous TP13 tonearm had no compensation for anti-skating force.

1972 The introduction of the TD125 MkII. The most apparent change to this revised model is the new TP16 tonearm which is now packaged as the standard equipment offering. The new tonearm features gimbal 4-point pivot bearings, magnetic anti-skate control and a new detachable magnesium headshell, the TP60. Effective mass of the new arm is rated at 16.5 grams. Refinements to the oscillator motor control circuitry are made. Platter bearings are all of the press-in design with solid tip shafts by this time.

The TD160 replaces the TD150 as the affordable but still Hi-Fi player featuring a similar 3 point suspension floating sub-chassis but with the new TP16 tonearm . Operation is pure manual but with an integrated cable operated tonearm cue. Like the TD150, the TD160 used a synchronous 16 pole 2-phase AC motor that derived it's pitch precision by locking on to the mains frequency the same as an electric clock motor from that era. Both TD125 MkII and TD160 share the same 7 pound die cast zinc platters and the same 10mm platter bearing.

At the same time a less expensive TD165 was offered with the TP11 tonearm. This new tonearm used the same gimbal pivot bearing, arm tube and head shell as the TP16 but substituted a weight-on-string style of anti-skate control and also featured a different counterweight.

With the TD165 begins a little mystery. The story of the nylon inner platter and 7mm bearing. This nylon inner platter and smaller bearing can be found on the TD165, TD166 (all marks), TD146, TD147 and some TD126 MkIII units. Alternately, the larger zinc inner platter with 10mm bearing of the TD125 MkII and TD160 can also be found on these same tables. Then, to make matters even more interesting, an example of a nylon inner platter equipped with a 10mm bearing has been found on a TD166. I am still gathering data on this issue. Perhaps, someday, there will be enough information to establish some pattern to this. At the moment no method of allotment has been determined.

1974 Presentation of the TD126 "electronic" with tonearm TP16. The TD126 replaces the highly regarded TD125 Mk II. Similar in dimensions and weight, the TD126 adds semi-automatic function to the tonearm operation in addition to a preset for mode of operation. (When equipped with standard Thorens tonearm) The TD126 featured lighted push buttons compared to the slider controls of it's predecessor. The TD126 shared the same basic layout and size of the TD125, continuing to use the heavy cast aluminum sub-chassis suspended by 3 conical springs and the same platters and bearing. Available speeds are now 33-1/3, 45 and 78rpm. The Mk 1 and Mk2 TD126 models continued to use the 16-pole AC synchronous motor from the TD125 MkII.

1975 The TD145 is offered. In essence a TD160 with automated arm lift and motor stop at end of play

1976 Introduction of the "Isotrack"-tonearm with a low effective mass. This is an updated version of the TP16 tonearm featuring remove-able 'arm wands' fixed by a collar lock very close to the pivot bearing. Moving the coupling joint closer to the pivot reduced effective mass substantially. The replaceable arm-wand of this tonearm is called the TP62. A later version of the isotrack tonearm, called the TP16-III used another style of arm-wand designated the TP63. Both of these tonearms rated their effective mass at 7.5 grams. These tonearms were suitable for use with phono cartridges having high compliance suspensions.

Optional with the Isotrack tonearms were arm-wands featuring integrated phono cartridges. The TPO63 and TPO70 were two such arm-wands. In cooperation with EMT, Thorens produced special cartridges of the moving-coil variety. Integrated arm-wand-cartridges TMC63/TMC70, phono cartridges MCHI and MCHII as well as the PPA990 and STA960 (pre-preamplifier and step-up transformer).

The TD126 MkIII is introduced. Some of its features include :
-DC 72-pole tacho-generator drive motor.
-New load-depending control of rotation (APC: automatic pitch control).
-Low mass "Isotrack" TP16 MkIII tonearm.
-Electronic frictionless shut-off facility.
-Additional motor for tonearm lift control speeds: 33, 45 and 78


The Receiver AT403, Cassette Deck PC 650, Sound Wall loudspeakers were introduced.

The Thorens "Rumpelmeßkoppler", a device for closely evaluating rumble noises of record players. Developed by Thorens engineer Ludwig Klapproth, the Rumpelmesskoppler (rumble measuring coupler) consists of two parts. One part is the spindle that is fixed with its lower end to the top of the turntable axle protruding from the platter. The other end of the spindle is shaped to a very fine point which is plated with copper and nickel. The other part of this device is sort of an outrigger which is hung up at the top of the spindle and supported along the spindle's shaft. The supports are made of high-polymer plastic and they glide virtually frictionless around the polished spindle. Fixed at the opposite lower side of this carrier is a tiny piece of vinyl record with grooves, onto which the cartrige and its stylus is put during the measurements. This rather stiff arrangement allows all rumble noises from 0 to around 500 Hz caused by the turntable or it's bearing to be detected and transduced by cartridge employed.

1979 Development of the state-of-the-art turntable "Reference" for measuring purposes. In spite of the stated purpose as a measurement tool, a series of 100 Thorens References were sold to customers. Unofficially, more were made but it is unknown exactly how many and what serial numbers those extra tables carried.
