Default New project: turntable!

Hi everybody,

I'm not much of a frequent poster but am always lurking in the background....
But since I have built my own turntable I thougt it would be nice to post some pictures.

It is based on an VPI platter bearing & motor. The arm is a RB250 with a pebbles counterweight & stub.

I'm using vibrapods between the two layers.

It is very basic but I like it that way!

In the future I want to make the chassis a bit heavier by using lead shot. And also try a motor from Scheu, which I suspect is a bit better then the hurst from VPI.

Any more details.....

Of course the wood is plywood (I think that's the english word for it....) There's no particular theory behind it other than I saw a picture of a commercial turntable which has the motor and platter placed in seperate pieces of plywood. I thought it looked nice and decided to use it.
Also I think it dampens vibrations better than 'normal' wood because it is made out of small layers of wood.

The platter is one made out of acrylic with lead. VPI has also put a layer of cork on the bottom.

The bearing is the older one from VPI which is attached to the plinth using three screws. It is the bearing which uses the plastic stuff...I think it is called Rulon.

I also have a slightly shorter bearing from VPI with a bronze sleeve, also attached via three screws. It looks a bit sturdier, but the Rulon is supposed to be better. I haven't tried the bronze one yet.

Only thing I have to say about the bearing is that it leaks. The oil wil just run out of the bottom. I don't think that's a problem because inside the bearing still is a bit of oil on all surfaces.
But you ca'n speak of an oil 'bath', which I think would make it more quiet. Not that the bearing makes any audible noise....

The motor is also from a VPI, a motor made by Hurst.
But I think this one can be improved. I use a (expensive) VPI round belt.

The counterweight on the arm is a Pebbles. It is made by a company over here in The Hague. It replaces the rear stub & counterweight so it can be compared to the Origin Live version.
This made a great improvement.

The cartridge is a Denon dl103 which is very very nice. I'm using it with a MF X-LPS which I am planning to replace with a tube phono-pre designed by Dick and Doede (that sounds nice...)
You can find the design at www.dddac.de. Here you can also buy the PCB's!

That's it!
