VPI Scoutmaster static


I´ve been having problems with static (seem to turn into loud static shocks - only in one channel - when touching anything metallic on my TT; CD player work fine, so it shouldn´t be the speakers or amp) with my VPI Scoutmaster for weeks now, but have not figured out what it really causes and what could I do about it. Bought today zerostat 3 (will arrive in couple of days I hope), I cleaned my TT platter with the help of clearaudio anti static liquid (and also surroundings of my TT), grounded the cable to preamp earth. is there´s anything else I could do? i suppose it´s the best place to ask for advice.

my vinyl system is VPI Scoutmaster (TNT feet, periphery ring and HRX center), Graham Slee Reflex Gold preamp, Sumiko Blackbird (Harmonic Tech and AU24 cables + Audio Analogue integrated amp + Dynaudio Audience 72 speakers) and all sitting on a solid oak rack (on linoleum floor).

Apologies for my English (I´m no native speaker) and if it sounds stupid, i´m just out of ideas and advice is much appreciated.

You said you checked the ground from the TT to the Phono Stage. Did you check the ground from the underside of the arm to the RCA junction box?

BTW- Your English is great!
no carpeting, pure linoleum floor. i was indeed wondering if the wooden rack might be the source of problems, will see to it, maybe put something in between the rack and TT (there´s indeed an IKEA around). the ground was hooked to the RCA junction box initially, i then checked it to phono stage (you can indeed put Graham Slee amp underneath VPI TT, so the ground reaches it), not much changes either way. thanks for suggestions.
Waltwalden: since you do have an Ikea and you have tried all or most suggestion's pertaining to grounding the table. Then I would at this time isolate the VPI by separating it from it's Oak rack would be best.
before parting with a rack (that was custom-made, although not really audiophile), do you think would a layer of "something" between the rack and TT could solve the problem (like a layer of anti-static floor vinyl, glass, laquered IKEA shelf etc)? had a VPI on the top of that rack the whole last year without problems. just putting a TT on an IKEA rack would not solve problem either as isolation etc will become issues. next thing is probably a proper wall shelf if i really have to do this, but before parting i will try all other DIY and zerostat 3.
