The Hub: Thorens TD-125: the table that couldn't get no respect


Back in the early '70's when I began to haunt "stereo joints" (as I called them), there weren't a lot of options when it came to turntables. The basics were Dual and Garrard, with the occasional Miracord (the US brand of the German Elac); later on, the flood of turntables from Pioneer and other Japanese brands hit. In those days, the table that was THE most serious turntable, sold with the best systems, was the Thorens TD-125. The absolute top table was the TD-125 with an SME 3009 arm (as listed for sale here).

I don't know this for a fact, but I suspect the TD-125 came into existence for two reasons:
1. While its predecessor, the TD-124, was the product of a Swiss music-box maker, it seemed more like the creation of a Swiss watchmaker. Its belt-drive plus idler-drive mechanism was hideously complex, and was undoubtedly expensive to manufacture;
2. The TD-124's organic styling and cream-enamel finish was very much a child of the '50's and'60's; the first time I saw one, I was reminded of mom's Sunbeam Mixmaster. As the new decade approached, the 124 looked old-fashioned, and its motorboard assembly seemed better suited to installation in a console, than standing proudly on its own.

The TD-125 replaced the 124 in 1968, crisply-bedecked in Scandinavian-style cabinetry. Its first iteration was made through 1971 (as seen here on the Thorens site, auf Deutsch) and the TD-125 mkII continued in production from 1972-1975.

At least by Teutonic standards, both tables are pretty simple devices, belt-driven tables with suspended sub-chassis for some measure of isolation against shock and feedback. An electronic speed control and strobe round out the design. It was available with Thorens' TP-16 arm, with the SME, or armless; a number of variants were made, including long-base models designed for mounting a 12" arm, and chassis designed for console-mounting.

If the description of the 125's design makes you think of the A.R. turntable, well, there are great similarities. Given its higher price (originally $280 vs. the A.R.'s $68), the Thorens should be better built, and in my experience, it is, and is quieter and more dynamic, as well. While the A.R. has often been tweaked and hot-rodded (thanks to parts made by my friend George Merrill, and others), the most-tweaked Thorens was the TD-160, and the 125 has been largely left alone. Haden Boardman wrote in Hi-Fi World of the deck's potential (seen here), but most 125's have remained stock.

Chris Thornton is a former Chicagoland Hi-Fi salesman entering his second decade as a sufferer of Audiophilia Nervosa. He picked up a Thorens TD-160 mkI at an estate sale, and following examples cited on Audiogon and the Analog Department (seen here), Chris cleaned, lubed and tweaked the 160, and was astounded at the improvement in its performance. "These old 'tables, you can't compare an old stock one with one that's been restored. Fixed up right, they just SING, and the build-quality is unbelievable"

Taking advantage of a steel-industry layoff, Chris now specializes in restoring and tweaking Thorens turntables, and today's subject is an example of his work. Chris usually installs a new Origin Live arm on the tables he rebuilds, but the vintage SME 3009 on today's 125 just FIT, both aesthetically and historically.

Chris' work not only offers excellent bang for the buck, but serves as proof that there are still plenty of opportunities out there for enterprising audiophiles with a commercial bent and some ability. It also shows that there's still a lot of great old gear out there waiting to find a good home and someone to put it into good working order.

So: keep hunting!

The arm-cartridge-platter system is yet another mechanical system in audio where one school of thought is to decouple everything, and another is to couple everything, to drain off energy. I think there are examples of each which work well, and make sense philosophically.

Yet another example where my answer to the question, "Which?"..is "both".
Hello all, First of all I would like to thank the numerous people who have expressed their continuous support and ongoing interest of our Thorens restorations and to Bill at Audiogon for submitting the Hub article. My work is merely the by product of a continuous passion and support of analog playback and my own personal interest in vinyl records. I'd say the toughest part of the entire restoration process is selling the turntables once they are finished! :) I would rather keep them all to myself but bills must be paid unfortunately.

Anyways, to address the question submitted by Jake4357; the massive plinth size on our current TD125/SME 3009 restoration serves dual purpose - to further decouple and isolate the main chassis and suspension from external vibrations (as Bill speculated) and for overall aesthetic appeal.

Lastly, we are currently working on our external website which will include detailed restoration pictures and descriptions of recent completed projects including: Lenco L75's, Technics SP10 MKII's and several vintage Thorens turntables.

Sincerely,
Chris Thornton
Bear with me -- I'm a little dim -- but what I think you (Stanwal) are saying is that the stylus creates micro vibrations which a resonate platter amplifies and feeds back into the stylus?

So is the ultimate solution for a Thorens user to replace the platter with something acrylic? Assuming such a platter is even available? Or is a non-resonant mat sufficient?
That is exactly it. A good mat will help a lot. I use to sell several in the 80s, still have a Platter Matter somewhere. I am not as familiar with the ones today. I think they are probably better and I am sure they will cost more. TTWeights make some interesting ones and the carbon fiber ones look good if a little high. I doubt if a new platter would be cost effective VS treatment of existing one.

Yup. There are German specialists who make replacement, higher-grade platters for the TD-124, but I'm not aware of ones available for the 125 or 160. I can tell you that those pieces cost about as much as a whole restored table from Chris!

Larry at TTWeights does make fabulous mats and weights, as well as a remarkable megabuck table. The carbon mats from Austin Jackson at Boston Audio are an alternate route, beutifully made--but they're not carbon FIBER.

The joy(?) of audio: there's always SOMETHING that needs tweaking!

Thanks, all, for the comments.
