Based on your responses to Dave and Ralph, I am now thinking that I got it wrong. Am I now correct in thinking that the tonearm per se is not necessarily vibrating but that the hum you hear (over the speakers, I presume) is ameliorated when you grasp the arm tube? If so, this makes much more sense, and I agree with Dave. But I will throw in another idea; the arm tube structure is grounded to the arm pivot (i.e., makes electrical contact with) the bearings only. I once had a maddening hum problem that was only cured when I took my tonearm to Herb Papier (the inventor and original manufacturer). Herb lived about 10 miles from my house. Herb took my arm, and before my eyes he tightened the bearings by a hair, and the problem was gone. That has to have been nearly 20 years ago, and I have had no recurrence of the problem. Problem is you need a Herb or a Tri to do it so as not to over-tighten the bearings.
Debuzzing a Wheaton TriPlanar problem
My original dealer is out of business now, and the only TriPlanar contact listed on Google does not respond. My problem: when initially turning up the preamp gain, the tonearm - yes ! - emits a loud buzz. All I have to do is grasp the shaft - wrapped in an inert cover - and the buzz ceases (mostly) for the duration of my listening session. I've grounded both the tonearm and VPI table in addition to the ground provided on the cable itself, and still the problem persists.
Might the Cardas arm cable not be shielded properly ? I have not a clue about rewiring a tonearm myself and cannot locate anyone in NYC to do it.
