-- 1958-1961 Introduction of the models TD184 and TD134, both with the BL104 tonearm, The TD184 featured semi-auto start and stop operation with a provision for starting with a 7, 10 or 12 inch record. The TD134, however, featured semi-auto stop operation. They were both equipped with a switch to allow manual operation. These are not changers, the operator loads and unloads the record.

-- Thorens TD184   (these two from Ferruccio's collection)

 

-- 1961 - Introduction of the Thorens BTD-12s tonearm, intitially for use on the TD124 and the TD135.

-- 1961 - The TD135, (promoted as the inexpensive studio machine for amateurs), equipped with the BTD-12S tonearm -- is introduced. It featured semi-auto operation in that it could turn itself off at end of play, like the TD134. It was positioned upward within the Thorens price line-up directly below the 'top of the line' TD124.

-- These models, the TD134, TD184 and TD135, were 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 The BTD-12S tonearm was well received at its introduction and was the company's top tonearm offering until it was superseded by the TP14 in 1966.

-- The Telefunken Studio 220 was produced this year.

Notes on the Studio 220

circa 1961 and concurrent with the introduction of the TD135 and the BTD-12s tonearm.   This model's uniqueness is with its features as well as its cosmetic trim appointments.

--Manufactured by Thorens to custom order for their customer, Telefunken.

--It combines the chassis, drive system, platter, platter bearing and tonearm of the TD135 with the semi-auto features of the TD184 which included auto-start as well as auto-stop or switch to manual.  The TD135, by comparison provided auto-stop or manual.

--As with the TD184 there is a setting for the three different record sizes at the start function.

--Cosmetic trim differences include a Telefunken name plate on top of the BTD-12s tonearm pivot bearing case.

--There is another Telefunken nameplate at the speed switch lever

--The Speed, on/off and pitch knobs are unique to the model

--It has a two-tone paint job at chassis exterior.

--Thorens did not produce this exact design under its own name.

-- Based on the TD135. but with it's own unique cast chassis plus additional gears, pulleys and levers, arms etc. 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. **Video Link**

* Left. Robert Chamber's Thorens model TD121. Equipped as it might have been purchased new from a Thorens dealer in North America.
-- Promoted as a Single speed turntable with operation at 33-1/3rd rpm and with variable speed adjustment of ±3%. However, and as with the TD111, speeds of 16, 33-1/3rd, 45 and 78 rpm were possible by repositioning the idler wheel against the stepped pulley underneath the platter. ---And you had to remove the platter to do this.
-- it uses the lighter bearing of the TD 135 (10mm).
-- It has the one piece non-magnetic platter of the TD135 (cast zinc)
-- Speed pitch adjustable to within ± 3% and strobe patterns are found in the center of the platter mat about the spindle pin. to refine your speed setting.
-- No spirit level,
-- No clutch decoupling.
-- Otherwise it shares the same chassis casting and drive transmission of the TD124

 *TD111 TD111 TD111 (click for full size image)

-- Above three photos of a TD-111 were sent in to this site by Pat Omalley back in 2004. These photos represent the 'as found' condition when Pat first purchased it. For more photos of this unit and info about the restoration see this link.

-- The TD111 includes the "essence" of the drive transmission used on the TD124 but with 10mm brg and a 12 inch diameter 8lb one piece non-magnetic platter. It was sold as a single speed model and the control knob indicated as much by not including any speed value but while including a ± 3% speed pitch adjust as was seen on the TD121. A strobe pattern was imprinted on the platter mat center for 60hz operation at any of the four speeds. Further, it was possible to switch running speeds between 16, 33, 45 and 78 by manually re-positioning the idler wheel against the stepped pulley. (After lifting off the platter, of course.) Not a convenient speed change, but still possible. After restoring his with a refinish to the original plinth and mounting a more recent tonearm Pat described his as having "good bottom end with tons of weighty midrange". I'm thinking this one should rock and roll just fine.

-- Price for the TD111 was set at $60usd. Add another $10 for a cabinet-finished in either Walnut, Ebony or Mahogany. A mounting board for the tonearm of your choice was available at $4.50. Bring your own tonearm. This was 1962.

-- In Joachim Bung's Book, Swiss Precision (2nd ed) he tells us that the models TD121, TD111 and TDK101 were only available in the United States for a short time. And that Thorens did not make them available anywhere else.

-- Note: presently I have no photos of a TDK101. However you can find an advertisement that promotes one in the above noted book by J.Bung. (Page 51)

-- The info I can find tells us that the TDK101 was made available as a single speed turntable kit (33-1/3rd rpm). Promoted as "A single speed turntable kit for the do-it-yourself hobbyist". Among its list of promoted features were: 10 inch non-magnetic platter, (doesn't specify weight), Variable speed control ± 3%, Belt-idler drive system, operates on 117 vac @ 60 hz. (for North American use)

-- Price for the TDK-101 was set at $47.50usd, add plinth in Walnut, Ebony or Mahogany for $10.00 and the mouting board for $4.50 as was offered with the TD111 in the same ad.

-- 1963 The Thorens company merges with Paillard SA, Sainte-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.

  The Thorens TD150 TD150 (click for full size)

-- 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 means 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 in its tip while turning 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.



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. Minor changes in the controls. Also revised was the TD135, now TD135 II. Note; even though the main turntable operations had moved into Lahr, Germany the TD124/II models continued to be assembled in Sainte-Croix from parts inventory on hand.

-- 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. Like the TD150, it also is a "purists" model with all manual controls.

Early production units also share the same platters and bearing shaft with the TD150. Early TD125 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 TD125 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.

-- 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. On the mkII a cue knob, up front, operates a cable lift system that has been seen on several models going forward.

-- 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.

*TD160 Ad Magazine ads from the period  TD160 ad (click for full size)

The TD160 replaces the TD150 mkII 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. The TD165 used a 7mm diameter platter bearing fixed to a resin inner platter. The motor and pulley were also different from the TD160.

-- 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.

Editor's Note: So far I've been unable to find any advertising documents for the first version TD126 dating from 1974 or 1975.  No magazine reviews either.

The TD145 is offered. In essence a TD160 with automated arm lift and motor stop at end of play  (editor's note: apart from different notation around the on/off speed change knob, the TD145 appears very nearly identical to the TD160, until you remove the bottom cover and take a look within.)

*Thorens TD145 magazine ad TD145 advert (hint: click for full image)

-- 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.

*Thorens arm wands (click thumbnail for full size image)

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 Thorens "Rumpelmeßkoppler", a device for the measure of the rumble noises of record players.

*Rumpelmesskoppler

Above left, design sketch. Above right, actual tool.

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.
