Nude Turntable Project

Lewm - I've often wondered how the heck they can keep the thread from slipping down the smooth sides of the platter.

Lewm - Depending on my mood I do one of two things before a listening session in front of the Verdier.

I dance a little dance or
I get down on my knees and recite a short prayer in front of it.

So far the same piece of silk thread has been on their 9 months. It must be working.

cheers

I'm sure it does; I've never seen the thread slip on any of those. That was part of my point to Dover. I thought also you were going to take issue with his idea that the Verdier needs a "stronger" motor. To my way of thinking, the Verdier is one of those in the "hi mass/lo torque" grouping of belt-drive turntables, a grouping that I regard highly for sonics and which includes the Walker Proscenium. Whatever one might think of the Verdier, I believe it was designed "as a whole", and the use of a relatively weak motor is intentional. (Actually, isn't the Final Audio Parthenon also in this group? Maybe it has a high-torque motor. It sure has a high mass platter.)

I just downloaded the Teslameter 11th App onto my iPhone and it's very interesting.
It measures an electro-magnetic field in either Micro Teslas or Milli-Gauss (1 Tesla=10,000Gauss).
Just sitting in my listening chair gives a reading of 43uT or 590mG whilst at the turntable platter I can get a reading from 92-over 200(cut-out point) uT or 590-over 2000mG.
Readings UNDER the naked TT-101 are all over the 200uT max limit.
The readings change with power on or off so a complex study is required.
Because of my 3 tonearms.....the position of each cartridge traverses a different path with the cartridge passing over the transformer reading the highest.
Of course...all the cartridges at their inner-groove points are directly over the motor coils and the reading goes off the chart in all these cases.

The interesting thing is no difference in sound is heard by me as each cartridge passes over different reading points...and the arm passing over the transformer sounds no different to the other arms in intrinsic quality.

As a side-note....in this months issue of Stereophile with the 2013 Recommended Components.....for turntables ranked A+ and A.......76% have their motors mounted in the plinth close to the platter.

If Thuchan can download this App to his iPhone and demonstrate that the EMT 927 provides plenty of magnetism.......it may be possible to make a case for the beneficial effects of this ingredient? :-)

Henry, Don't own a Garrard 301

Sorry Lew.....I knew you had an idler and was just too lazy to look-up your System Page.....
It would be interesting to check your Technics SP10Mk3 which has the motor with the most torque (power?).....?

The shielding on the L07d looks like galvanized steel sheet. I think that it improves with the addition of extra shielding because there are some gaps and that in this case more is better. Yes it does resemble a flying saucer in profile and is , almost, completely encapsulated in shielding.
Another interesting design is that extensive shielding is used below the motor.

Btw it is not my intention to criticize the design. It is simply a different approach to building a motor.
I very much like its speed sensor approach and the clever way the main rotor magnet relieves some of the platter weight from the thrust bearing.
