Darren,
I am afraid there is not much room for any funny business!! under the platter.
I have modelled the complete assembly on CAD and I can tell you there is very little room.
The design of the platter DD assembly is such that the platter sort of wraps itself around the motor assembly and the PCB. Hence the inverted dish shape of the platter which of course is a large part of the problem.

There is also a thick layer of rubber bonded to the underside of the platter which would not be practical to remove. There are other platters such as the SL1500 which do not have any rubber bonding, and which could be contenders for your suggestion. However they will not work on the SL1200 as the magnet rotor assembly differs substantially.

So we must resign ourselves to either putting something on top to improve the dynamics/sonics or look at an alternative platter design. Which in itself was not an easy task as the low profile of the motor assembly limits the options.

Just had a reminder of the ringing platter a minute ago. Went to put on a new record that i could tell was loaded with static. I got to about 6 " of the TT and felt a belt through both hands and ring of the platter as the spark connected.

Colin,
That is an unbelieveable amount of static from a record and would not do the ICs on the PCB any good if it happened to often.

Actually , im getting a belt just touching the buttons on my cdp so i appear to have a problem. My system hasnt sounded so good the last few weeks so i need to look at it.

Colin,
If you are using one of those so called mains conditioners or other devide interceded between the mains supply; Then be careful if you are not an electrical person

[colinB]

I use a plugboard where the inputs are wired in parallel , supposedly to eliminate cross talk but thereare no filters on it.

[Mike_New]

Collin,
If you are getting a belt just touching the CDP buttons, then you may have lost an earthing connection somewhere between the plug board outlet and the main earth.
Disconnect all the equipment from the plug board and check for any voltage between the earth pins and a known good earth. A water pipe can be regarded as a good earth reference, however the caveat here is that water pipes are now often made from plastics. You will need to determine this for your self.

Thanks Mike, i will check.
Sorry for the off topic, please be free to remove.

My Mike New platter arrived today with Copper top plate, it's a thing of beauty!

Hi Andrew

I see you have an SME V , be interested to know how you get on with the platter
