A Shocking Experience


Recently, I have begun to pick up electrical shocks from my TT. I believe it is static because once it discharges, I can touch the platter again without shocks until I walk across the room again to change LP. This just started happening a few weeks ago and is quite annoying because the charges are quite large and even produced a small spark that was visible, I really felt that one! The TT is TNT VPI, and all LPs are first cleaned with VPI cleaner and are all treated with LAST preservative. The room is carpeted and I am not barefoot. The ground wire is intact and the connection seems okay. I normally walk about 15 feet across the carpet to change the LP and this occurs each time I put a new LP on the platter. Any and all advice would be greatly appreciated.

If you've got air conditioning / dehumidifiers running, it is possible that your room lacks the humidity required to "dampen" static electricity charges from building up. While it is always a good idea to make and break all the connections on your system occasionally, i would invest in a small meter that measures the relative humidity in the room.

As a side note, you might want to rig up some type of grounding post that you can touch prior to working with anything in your system. Some people attach a small metal plate that they attach to a convenient yet out of sight location on their rack or use one of the support rods on the rack. Grounding either of these and then touching it prior to handling your gear minimizes the potential for damage to your gear. Since static electricity can reach levels into the Kilovolt ( thousand + ) level, it is quite possible to whack something up in the matter of micro-seconds that it takes for static to arc from you into the equipment.

Yes, it sounds like you are the static generator, and not the turntable in this case. Don't drag or scuff your feet on the carpet, and you'll generate less static.
