serious static !

Post by klipper » 11 Feb 2019 19:39

hello all. the other day my wife went to turn over an lp we were listening to and there was a pretty powerful charge of static electricity. i have the uncle milti antistatic gun and record doctor antistatic brush which i use. never experienced this before . any thoughts, ideas or suggestions would be appreciated. thank you, bill :D

A humidifier would help. It's that time of year.
That static charge probably came from you walking over to the turntable.

Cheers,
Alec

Really dry, cold weather seems to do that to me but since I live near Vancouver, those conditions don't occur that often. There was once an occasion, when I too went to remove an LP from the platter and the (felt?) mat lifted off with it - stuck together surface to surface.

As Alec said often you build up and carry the charge over to the electronics by walking across the room. The winter air is so dry from heating that it promotes this static buildup. One thing that I found helps is to create a "Touch Point" near the stereo system made of a small piece of copper (circuit board, copper flashing, copper shielding tape) with a wire soldered to it that is connected to a ground such as the screw that holds on the electrical outlet plate, or the grounding terminal on the back of your preamp - BUT with a one to two megohm resistor in series with that wire. Then as you walk up to the turntable you just touch the "Touch Point" before you touch anything else and the static is drained safely away. The high value resistor limits current so there is no ouch-spark flying from your fingertip and just a non-eventful draining away of the static from your body.

Interesting. I can picture what you're talking about, but do you have a photo of what you've done? (I have lots of copper shielding tape from a Fender Stratocaster project!

Yeah, even with the Milty I'm getting lots of static even with the moderate temps! (Sometimes the leather TT mat sticks to the record as I'm lifting it off the platter.) Oy.

I had some minor static problems, probably not as big as yours, but putting an extra lp under the one being played solved the problem.

i find anti static arm, (a brush + arm while playing records) very effective. you can ground the arm to a receiver. no static discharge since use of that.

Here's a picture of one that's on a bedroom system. Everytime you would pop out of bed to change or pick an album - Whack! Seems a lot of static electricity in bedrooms.

You can see that a strip of copper foil tape is stuck to the shelf the turntable is on, to use as a "Touch Point" to touch before touching anything else. A green wire is soldered to the rear of the copper foil tape and runs to a 1 or 2 megohm resistor soldered into the back of a Banana Plug. A Banana Plug will plug right into the third ground connection of an electrical outlet on an outlet strip or wall outlet. In this case I used an adapter from an electronic supply house used for wrist grounding straps and workbench static control mats for technicians to be able to avoid damaging sensitive components. It's a plastic electrical plug with a Banana Socket on its rear, and the only metal connector that goes into the outlet is the third ground pin, with the other 2 blades just plastic. Yet another approach is to put a spade terminal on the end of the resistor that goes to the outlet ground and put it under the screw that holds the outlet cover on.

The concept is to safely and without drama drain the static off yourself before touching anything. The resistor is a current limit so you don't feel a sudden shock as it slows down how fast the static drains off of your body. I touch for a count of 2 seconds...

I would first check the electrical outlet with a plug-in tester to make sure there is no ground fault, and it is wired correctly. Always be safe!

BTW, I pushed the turntable back to expose the solder joint, and unplugged the grounding connection for the photo.
