Nude Turntable Project

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?).....?

Lew
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.

Lewm - 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.

Lewm - as far as I can tell from pics of the Final TT - both the Final and Platone Verdier use thread but similarities end there. they are totally different executions - as different as an ESL and Dynamic Cone speaker. I am sure Dover will enlighten us more about his Final TT.

The Verdier is outside of the box as you can see from your dealers setup. It is like your childhood merry-go-round. Both the Platine Verdier and merry-go-round, once spinning need only occasional jolts / pulls from the motor/person to keep them going. The motor can be seen cycling on and off. If setup properly you can in fact turn the motor off and on for a short period and not notice the pitch change. Try that with your Dealers TT - I am very curious what you will hear.

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.

You are absolutely correct and the Verdier is not for everyone. But here is an most important consideration. We all hear about how powerful this or that one TT is; how torquey it is. The big motor. How quickly it gets to speed.
Well I used to race on land, water and snow. if you ask any veteran racer - you have a race to run - you must stay at a constant speed and there are alot of turns peaks and valleys on the race course. The first half of the race will be easier to navigate over while the last few turns will be tighter. The magic question.

if you had to choose -do you want better torque or brakes based on these conditions ?

The drivers/riders I knew including me would say that braking is more important. Now with a TT both are important but ask yourself how does your TT brake? Is there a motor involved, a brake pad that moves in and out. Does it need to attach to a spindle, belt or thread to have the ability to brake. Well the Verdier uses no motor for breaking. Braking is done with the replusive force of the magnets. It is natural physics dealing with the record behavior. Am not aware of any other TT like this plus it has no thrust bearing.
If you cut the thread while it is turning the platter turns for about 1/3 the time than when turning as a whole system connected to the motor pulley and just turning the motor off.

Also in keeping with Henry's Nudie thread the Verdier is as nude as you can be imo. This design also however leaves it open to audiophiles mods. The motor can be replaced with anything along with any kind of belt or thread. Once you replace the original motor and thread system you have defeated JC Verdier's well thought out design. Your dealing with a platter system that has braking action in it for a reason. Your on your own. What other TT motors have been built to work with this type of platter system. Hey - who am I to stop someone from putting on a TW motor, or a VPI one or lets see how about a Galibier one. Heres a good one. An sp10mkii set up beside with a special acrylic platter set at the right height so thread can be installed. hows that idea ? it comes from another Verdier owner. As long as you're happy I guess. Crazy hobby.

Cheers
