Felt platter pad? Did you try a different non static felt pad?
Also is the platter spindle bearing grounded?
Are you sure the arm tube is grounded? (If conductive)
Just doing a quick goggle search this came up.I have no idea how it will affect the sound.

It may solve your static build-up problem though.
