3-Speed Belt-Drive Suspended Chassis turntable with electronic speed control available in mkI form (1968-1971) and mkII (1972-1975).
A prefix models came fitted with a tonearm but no base, B came with a base but no tonearm, and AB was a complete unit including base.
The TD125 has taken a giant step in banishing rumble, with solid state circuitry replacing the conventional mechanical methods used for speed control.
This reduces the number of moving parts and total mass so frequently a rumble producing factor.
Motor rotor velocity, another rumble originator, is precisely governed by a dependable Wein Bridge transistorized oscillator.
It's frequency is varied exactly (by a gold plated switch) to change the speed of the motor and these adjustments may be viewed instantly on the built-in stroboscope.
Motor rotor speed on the TD-125 has been reduced to an incomparable 250rpm at 33 1/3rpm turntable speed.
By combining this factor with solid-state circuitry and the Wein Bridge oscillator, Thorens has reduced rumble to an infinitesimal and inaudible -48db (-68db weighted); less rumble than any other turntable on the market!
The tonearm and turntable platter of the TD-125 are mounted on an independent chassis.
This unit is then shock mounted to another chassis which houses the drive system and controls.
As a consequence the tonearm is protected against shocks when the controls are operated and acoustic feedback is minimised because of the absence of vibrations.
Vibrations are further decreased by the precision polished, self-lubricating bearings of the turntable platter.
Drive method: Belt driven
Speeds: 16, 33, 45 rpm
Motor: 16-pole synchronous motor
Platter: 7 ibs, 12" diameter, anti-magnetic die-cast
For the money, I can't think of another second-hand player which offers so much for so very little - Haden Boardman HiFi World

One of the best thorens belt drive

I got this table with a totally botched repair attempted by the Canadian distributor. Wrong transistors even! Otherwise in good shape though.
10/10 - why? It redefined my expectations of what performance a turntable was capable of. Added a Platter Matter for a further improvement. This turntable deserves competent service, so I think the comments about service by flavio81 were laid at the feet of the wrong party. You can't blame a well designed table for incompetent service people. I have repaired my share of service disasters on these.
Buy one and care for it. If anyone has a Platter Matter available as a new product, make it known please. They work extremely well.

Sound quality = near 10/10 after servicing and modifications to kill the resonances inherent to a thick mettalic suspended top plate.
I'm giving it a 9 instead of 10 just because servicing an unit that is not in perfect shape can be laborious. Also 1 point less because of the stupid, idiotic clutch on the motor spindle, and because the way the spindle is placed, it's all too common for an idiot owner to transport the turntable platter on, let the platter slip and whack the motor spindle knocking it out of alignment. Which will set back Flavio lots of hours to straighten it out.

Yes i agree a very well made and good sounding unit. certainly the best Thorens i have used, very good partner for SME 3009 arms.

Bought the TD 125 in 1974! Still working like a charm. Is this world record?
