Thanks, I contacted Sota and they said the chassis ground should be connected to the preamp. I still get a lot of static this way. The bearing well is some sort of Teflon or plastic so I can’t add a wire to that. I may revisit my tonearm wiring just to be sure I didn’t miss anything there and then try a humidifier or something like that.
My SOTA cosmos has never had any issues.
mc, if it is static electricity on the record try one of these. https://www.sleevecityusa.com/Antistatic-Record-Cleaning-Arm-p/tac-01.htm
The bristles are conductive carbon fiber and the arm is connected to ground so it shorts the record out while it is playing and sweeps any incidental dust out of the way. The static is being created by the stylus rubbing the groove. Unfortunately for us vinyl is at the very bottom of the triboelectric series. It loves to hold on to stray electrons.
When you set up the sweep arm you want to adjust the weight so it just barely touches the record. The sliding weight gets knocked out of adjustment easily so I slide it all the way to the front and crazy glue it in place. Then I adjust the tracking force with the threaded counter weight at the back. I put some thread locker on it so that it holds it's adjustment.
I have been using a conductive sweep arm for decades and never have any problem with static. I would never live without one.
Thanks I’ll give that arm a shot. I do feel that because my Rega and thorens tables play without any static issues there could still be a grounding issue with the Sota. Maybe I didn’t ground the arm and chassis correctly so I’m gonna re-visit that wiring. The jelco arm has two ground wires so maybe something is off there
If you want to ground directly to an outlet you will wrap a wire around the screw that holds the outlet cover to the outlet. That should be a good ground source. It looks like this!
Great, thanks for that! I’ll give this a shot before I mess around with tonearm wires. Just curious if it make a difference if the wall outlet accepts two prongs versus three of I go this route? I have two different outlets near my rack and have both options.
sorry everyone for all the questions. Up til now I’ve just had to plug everything in and not think about all this.
I doubt that the 3 prong outlet is grounded. Over the years it was most likely replaced and someone used a 3 prong outlet ( with no ground ). You should have it checked out . An inexpensive voltage tester like this will verify if that outlet is grounded!
