i recently had a question on static ,which i asked Jonathan Nye about he suggested to use a continuity tester and check the earths,,, make sure all the earths were in contact with the Chassis , the arm board /arm and bearing spindle,, i had removed the paint under the chassis where the screw comes through ,, this gave a better earth contact ,,,because the paint was acting like an insulator,, then checked the Arm board earth to the spindle,,, with a ceramic bearing fitted ,, to make sure the earth loop was completed ,,,it was,, so no problems with the earths to the phono stage and out down to the Russ Andrews Rf block and out to the earth in the house,, i then checked the TransRotor sweep arm that has an earth ,i was in for a surprise,, although the body was earthed the arm it self was not ,, i think this was due to the clear coat that was on the sweep arm, or the hole it sat in having some thing left in the hole after production,, i had to drill the hole deeper ,, Tap the hole under the top of the balance part of the arm , this now is earthed,, so no problems with static ,, even with the ceramic bearing ,,
