Thorens...

[nar]

Hello to you all,first time I make a post on this forum.I recently bought a new table,analog reading.It's a THORENS TD 115 MKII,I had it second hand so it was kindda cheap(70 euros).Works perfectly,and cartridge associated is the Shure M95EDM.

I don't know much about analog tables but I found the combination of the 2 awsome.Much better than my previous attempt. Especially on 33/1/3 LP of the Final Cut by Pink Floyd,the sound is rich ,well detailed,subtle,huge and powerful sometimes (depends of the mix and age of vinyl).

I am shocked by all those listening qualities.In my opinion gets so much better and expressive than CDs!!!....

Can anyone advise me on best way to tune weight and antiskating,etc.Is it possible to modify electronics inside (especially speed regulation)???

Please answer me !!!!!

Best regards

Anael

PS:I have an Alephono in construction.To match the THORENS...

Welcome nar

(says he with 5000 LPs and <50 CDs)

Can anyone advise me on best way to tune weight and antiskating,etc.Is it possible to modify electronics inside (especially speed regulation)???

I'm not that familiar with either of these... so can't help with the details. Making sure that the cartridge alignment is right makes a big difference. There is a thread with a number of attached templates.

Dig thru the analogue forum, there is much to learn there.

Hi nar,
I don't want to bring you down, but the TD115 belongs not to the highly recommended Thorens-tables. It represents the attempt to trick physics with electronics... The platter and the whole device is light-weighted, and I guess by your question there might be some problems covering that issue.
You will find that e.g. the models TD150, TD160 and others won't have speed stability problems. These are robust as sewing machines.
Of course you can work over the electronics board, check transistors and caps!
Anyway, have fun with the device (and keep an eye open for another thorens... ;-)

How is the TD-145 regarded? I've had mine for just about forever.

should be ok. There are different versions around (of TD150, TD14x, TD16x): some have plastic inner platters, some metal. There are two different spindels as well: one is 7mm, the former (?) is 10mm in diameter. The thicker one is regarded to be superior, though I have never compared those directly. The bearings are different here, too.
There have been several posts in german forums regarding the grading of different thorens editions, however, it seems somewhat unpredictable which features a given edition has.

Hi all,

Anyone with some experience tunning the TD160 springs?
Besides, my thorens has some play with the bearings of the arm, does anyone know how to adjust this?

Thanks, Rüdiger.

On my 145, both the removable outer platter and the fixed inner platter/spindle are metal. The inner platter measures ~ 135/155 mm depending on where you measure.

Thought I'd add a bit. The Thorens TD-145 is exactly like a TD-160 with the addition of an electronic arm lift.

As for suspension adjustment, if you have a very solid foundation to set the table on, the springs should be set as soft as they can go without bottoming out when lightly bounced. If, however, you have a springy floor and have a problem with footfalls causing groove jumping, try adjusting the springs tight so that the sub-chassis and main chassis are as one solid chassie with no suspension. This practically eliminates footfall problems. The motor on these is so small and smooth running that I could hear no extra noise when doing listening tests even though there was no isolation being brought about by having a suspension system.

Hi to you all.I have upgraded the td115mkII with a New Grado cartridge,the black prestige one.Amazing!...

All my LPs sound more transparent.

But...still some unsatisfactions.I do not plan to buy a new table.I would like to improve speed stability.I changed the belt for a new one,exact size.The old one was a little loose

Does anyone know how to improve speed stability on this model?

I know I could
1) add some mass inside the metal plate.The question is to do it equally ,and which is the limit?Afterwards the motor will be heavily driven.

2)change the ugly stoboscope with a neon wired on the mains.It is the only speed control but not accurate enough.As the frequency of the AC line is to vary +/-4%.I have in mind a ne555 to get a precise 50Hz flash with leds.

3An external motor...with no belt but a single wire instead,going outside the metal plate.With a DC motor turning very fast seems the speed for the record could be more precise.I could power the motor with a reulated variable DC supply to tune speed precisely(i.e.LM317 with multiturn trimmer).

what do you think guys?

Best regards

You could build your own AC power supply with tighter control over frequency (& grunge). Somewhere (in the intro forum i think) is a tidbit from a fellow who built one of these for his 220V/50 Hz Thorens when he moved to Vancouver.

I'd be interested in this kind of thing too. I have a 50 Hz Linn motor i need to drive.
