There is no relationship between fluid damping and VTF for any of the tonearms I've owned including a Jelco SA-370H. In other words, fluid damping has no affect on VTF and vice versa. VTF is a function of the cartridge being used.
My Jelco SA-370H came with a little vial of damping oil. I didn't use silicone fluid in it. However, both my SME III and SME V used silicone fluid, but I don't know the viscosity. I just used the SME silicone fluid that came with each tonearm.
Good luck,
John Elison

  Waaaaay out - as the manufacturer stated theirs was 500cps (quoted on VE; 2011)- obtainable as Ansmann "Dr Liquid" Silicon Shock Oil (50ML) - cheaper than Jelco!

    There was a long discussion about it on VE
    The discrepancy between the two numbers is huge :)...
    60,000 cst is like honey, 500 cps is like motor oil.
    
    Edit...My dyslexia kicks in all the time it is Centi Stokes as in cst and cts....

      Dammit - was going to remove the post as saw it/you referred to SME (2/3).
      Anyways, 100,000 cps ("Dr Liquid", again) is still far too thick - though currently use it neat as it doesn't cause 'problems': the original SME part was specced @ 200,000 cps.
      Having spoken to SME a few months back (not for those of a nervous disposition..) they apparently now don't recommend using damping at all..
      Never set-up my Jelco 750D - had for over 3years - looks a 'dud purchase' in retrospect!

        I had to double check it because i got the original info from DIY Audio, the second search confirmed the first info....so there you have it. John asked so i complied. You brought in doubt, now we are even, FWIW i have no info on the Jelco.
