Default Thorens TD125 mods

Some months ago, I got my hands on a TD125 in good condition. The bearing seems to be fine, electronics OK, plinth OK, no arm and dust cover though....
I do happen to have an SME series II improves, though, and a V15VMX.....

Does anybody have a drawing of the plinth innards?? I thinking of making a new hardwood plinth with real a glass dust cover..
Any suggestions for other PROVEN mods ??

( And i just got a confirmation on winning an auction for 100 mint Deutshe Grammophon records and appx 80 other classical records all at appx 1 each, - in addition to all my old ones...
better get this thing up and going real quick!!

Haaaaaa thoses old thorens 124 and 125 ! I love mine.

I had very results removing the suspension (remove the springs and turn over the whites adjustable caps) and using a more heavy wood base.

This only work if you have concrete floor as I have or a very solid and heavy rack.

I did add some dynamat under the pinth and at some spots near the motor and the pivot.

Check if the speed is very stable, if not change the capacitors.

I use an heavy puck in the midle of the disk since I don't have suspension anymore. Change the mat for a carbon one.

The sme are very good but would benefit from a rewiring using thin cardas cable. I have very good sound using a dl-103 on a sme II unimproved.

Hi franksmith,
Now that is very pretty indeed. My table is a Thorens TD-125 MKII. Completely stock but rebuilt by myself. I'm about to install an Ortofon 540 cartridge to replace the VMS 30E MKII on there now. I use a "Platter Matter". I have found these tables to be very reliable after setup. I've repaired many for other people.

Your puck may cause excessive wear in the thrust bearing.

-Chris

What do you mean? The whole TT assembly is mounted to the plinth with just four screws. Measure the plinth inside and the position of the mounting brackets (wood).

I have a plinth made (it will have a 2" rim and will differ from the original thorens box) from 3 layers of 3/4" baltic plyood.

I would not recommend getting rid of the suspension - this is totally contrary to the thorens design goal of decoupling the thorens from footfall and other noises. The thorens therfore is even better then the transcriptors hydraulik - which I have sitting on a metal laminated mdf board sitting on an inner tube.
The thorens is excellent when it comes to noise - very quiet, no motor noise, rumble. Easy to test for yourself.

I also got rid of the bottom cover (made for my #1 TD 125 a aluminum frame instead, as I needed something to mount the cones to, that it is sitting on now.) as it increases the noise level - like an echo chamber.

Recommended - clean the bearing assembly and fill in new oil . On ebay there are also some polishing kits available for the bearing assembly.

PS - forget about the dustcover - they also act like an echochamber during playback and are just a nuisance overall.

Thanks a lot guys...

PS - I wasn't thinking of using the cover during play, - only as DUST cover between sessions.

Any more ideas out there ???
