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.
