SME 20/2 Static Electricity


I love my 20/2 but I get a lot of static electricity on the platter, especially in the winter.  
Maybe a platter mat will help.  Anyone had this issue and resolved it?  
I'm considering one of the many static removing devices as well. 
I never had this much static on either of the Clearaudio decks I owned previously.  Must be something related to platter material?
Thanks in advance for your help.

You're noticing now only because its extreme, but static electricity is always a problem, everywhere, and there is no resolution, only a series of things you can do to try and keep it down at an acceptable level- whatever that is for you.

My room never has gotten to the point of sparks zapping fingers yet I know its there because its so easy to hear the difference when its gone. Or should I say less, since its never really gone.

The simplest, fastest and most cost-effective solution I have found is Static Guard laundry spray sold in stores everywhere but priced best at Walmart. Don't spray directly over records but do spray it all around the turntable and all components. I like to spray over speaker cables just before listening. Having done this a long time now and by varying the frequency the improvement is noticeable after as little as 20 minutes. In other words if you haven't ever done this the improvement will be pretty big. But then if you spray again a half hour later it will sound better, but not as much. But let a lot of time go by and again it will make a big improvement. What this tells me is static charges are constantly building up and interfering with sound quality all the time, and remember this is even in my room, a room I don't think anyone would ever say even has any problem with static electricity.

There's other more costly and possibly more effective sprays you can find on Amazon. Haven't tried them because they are more in the nature of leaving kind of a film on fabric, like the office chair that zaps anyone sitting in it. 

There are also some grounding type contraptions that track along the record helping static get to ground before it can build up enough to cause a problem. 

Basically you're right, your new materials are more prone to static buildup, and a mat is likely to cause as many problems as it solves. Use the spray, use your Zerostat on the record, raise humidity if you can, and see where that gets you.

Does Static Guard leave any kind of residue behind?  
I would be hesitant to use anything leaving a residue around my pricey electronics.

I would not spray static guard on equipment.  If you have carpet, a light spray on the carpet will help to reduce the static buildup that you develop from walking across the carpet.  The best overall approach is a humidifier, get a good cold air humidfier and put distilled water in it (to prevent mineral deposits from the evaporating water).
snackeyp, I have a 30/12. I live in New England and as soon as he heat starts running the relative humidity drops like a rock and static charges everywhere become worse. Look up triboelectric series and you will notice that vinyl is way down at the bottom. It loves to hold on to electrons. There are few things that are worse. Aluminum however is in the middle and could care one way or the other. It is a great material to make turntables out of. Transferring electrons requires intimate contact. Rubbing helps a lot. The charge is generated by the stylus rubbing the groove with a force of 5000 PSI. You can create thousands of volts of static electricity playing just one side. If the charge has no where to go the record will hold on to it forever. 
The SME tables are suspended by rubber bands. You have to make sure the upper platform is properly grounded along with the tonearm. Next you have to discharge the record WHILE IT IS PLAYING. The best way to do this is a conductive sweep arm like this one  https://www.sleevecityusa.com/Antistatic-Record-Cleaning-Arm-p/tac-01.htm. The bristles are conductive carbon fiber. It tracks along with the tonearm picking up incidental dust and discharges the record along the way. Things like mats and Zerostats DO NOT WORK. Vinyl is not conductive. Discharging one side will not completely discharge the other. Remember the static is being created by the stylus rubbing the groove.
So make sure the upper platform is grounded and get one of these arms and I guarantee you will never have a problem with static again. If you do I will buy the sweep arm from you.
