Nude Turntable Project

Lewm,
I use the acronym above EMF to mean Electromagnetic Field. This will have an electrical component, measured in volts, and a magnetic component, measured in mG (milliGauss). The tester I used measures the magnetic component of an electromagnetic field in milliGauss.
With regard to the Q on DD's, I dont think it is ideal to have electromagnetic fields floating around the cartridge, irrespective of what type of TT is used.
Halcro,
Yes I got the pigskin. If I can get some from the local abattoir I'll try it over the preamp. Do you know if it is from an Australian Yorkshire or a Japanese Landrace ?

Excellent Design?

Of course :-)
But, my personal Favorite is Audiophile Rule No. 2

"when it sounds good to you, it IS good"

Dover,
Mine comes from Israel.....

I'm wondering if Idlers exhibit the same 'magnetic' characteristics as DDs seeing how they also have motors etc under the platter?
I suspect that the EMT 927 would react "positive' to a magnet wandering amongst its innards.......especially with its steel supporting frame?
Are you able to confirm this for us Thuchan?
And Lew.....perhaps you could do likewise with your Garrard 301?

Henry, Don't own a Garrard 301. Do own a highly modified Lenco L75. In fact the only parts from a stock Lenco that I use are the motor, the idler arm and wheel, and the platter. Where there is a motor, there is an electromagnetic field. Thus I am sure that one would be detected with a detector in the vicinity of the motor. However, I use the PTP plate, which is 4mm of solid steel between the motor and the underside of the platter. Moreover, there is about 2 to 3 inches of space between the motor and the platter, and the platter itself is heavy aluminum. So, the shielding is at least "pretty good", and the physical distance would help as well. These fields generally fall off in accordance with an inverse square law; the strength is inversely proportional to the square of the distance. In DD's with coreless motors, like the TT101 and the L07D, the potentially radiating elements of the motor are particularly up close to the platter.
