Default Repairing/Improving a Thorens TD-124 turn-table

Hello All,

Many years ago, when I was a soldier in the Royal Canadian Horse Artillery, I purchased a Thorens TD-124 turn-table sight unseen from a guy in Victoria BC. When I received it I noticed that the shelf that supports the tone arm mounting board had been cut off, apparently with a hacksaw.
I confronted him and told him I wanted my money back, to the last PENNY. He in turn told me that the shelf was not needed and that I should mount my tone arm directly on the base, and in any case, there was not enough room on the tone arm board to properly mount any tone arm. So I kept the TD-124 until, in the late Seventies, I built a black American walnut base for it. Then in the early Eighties, I purchased a Micro Seiki BL91-L and I stored the TD-124 away. In August 2018 I finished two prototypes of a tone arm that I had invented. I mounted one on my Micro Seiki turn-table and I decided to mount the second one on my Thorens TD-124 turn-table, after I had repaired/improved it. I decided to make the sawed-off shelf wider in the process since I could not return the TD-124 back to its original condition anyway.

I am attaching six pictures to this first post:

TD-124 as is, with a Pioneer dust cover
TD-124 as is, without the dust cover
TD-124 straight down
TD-124 with the proposed tone arm
TD-124 base only
TD-124 proposed new, wider shelf

In future posts, Ill document the machining of the Td-124 chassis and the replacement shelf.

Ralf

I truly hope that your posted pictures do not influence others to chop off the armboard bracket from their TD124 chassis. Most would regard this as absolute and unforgiveable butchery of the lowest order. As do I.

Hello carlthess40,

I described my tone arm in a recent thread, here:

A Revolutionary Pivoting Tangential Tone Arm

Some very smart people didn't understand how my tone arm works, until they watched the videos I had posted. So be sure to watch the videos too.

Sincerely,

Ralf

There is another similarly titled TD-124 thread you might want to look at, this one could be a candidate for merging with that one.

Restoring and Improving A Thorens TD-124 MKII

Most of your questions are probably answered in that one. (It's applicable to all 124s) Nice arm. I might want one.. And what Steve said on the butchered chassis.

Hello Kevinkr,

I am well aware of your TD-124 thread and have been following it almost from day one.

For the time being, I am only concerned with replacing the tone arm board support shelf that was removed by that clown in Canada.

To machine the chassis to accept the replacement shelf, I of course had to remove all the parts and there was plenty of dried hard old grease everywhere. So, when I reassemble the turn-table, I may very well need much of the information contained in your thread.

In the meantime, here are some more photos from the last few days showing progress of the chassis being machined to accept the replacement shelf.

Sincerely,

Ralf
