Yes, that would be really kind. Do you have the glass platter? It would be nice if you weigh it too.

I think that Planar 2 has smaller main bearings than P3. Something says to me that Planar 2 bearings are only 12mm ja Planar 3/P3 has 18mm. I am not sure if this is true?

the bearing is 8mm, that is the rod that slides into the bronze bush in the plinth is 8mm diameter.
The glass platter is 10mm thick and weighs just under 1.7 kg

I also have schematics for Rega's circuit to achieve less vibration result with this motor (practically just caps which changes the phase to different coils of motor).
Could you post or explain the cct?
The original cct are just 2 x 0.22 MFD caps on each winding. The new rega cct allows hard coupling of the motor on to the plinth. The 2 caps supply is still the dangle from an O ring mounting.....

The plinth is almost ready now and I am thinking the assembly of the Premotech motor.

Is it a good idea to cast the motor into bitumen? Sealing any holes in the motor first naturaly. Does it cause overheating or other malfunctions?

I am going to hardmount it to the plinth with a sticky paper (like in P3) put filling the motor cutout with bitumen would in my opinion absorb vibrations.

What do you guys think?

Hi Sella, now, in 2011, I ask you for the simple circuit that controls the rega motor.
My actual circuit ( cap + resistor ) make the planar a little fast.
Thank you in advance, Claudio
