You can get loopy dealing with a ground loop hum! And I've heard also, but cannot confirm, that DC interference on a line can cause trannies to hum as well. So who knows what you're dealing with.
IME, Herbie's stuff is good vibe control. So is Microsorb, which I like a lot, but it's now been discontinued so hard to get. There are other substances. I know one inmate who uses cotton very effectively with TI for mechanical damping. You pick your poison, but one will certainly work for you with the TI.
From CDC I got the info that at least on the speaker filters the guage of the ground wire DID make a difference. And I tested that minimally and found out that he was right. He recommended at least 12 AWG, and that's what I now use whenever I ground Ti-shield for this kind of filtering, even if it's not necessary for other AC filtering functions. Seems to work right, so why quibble.
But if you're grounding the TI from the transformer, I'm somewhat concerned that you may introduce a groud loop or other inadvertent source of noise by using a separate plug. Why not find the place that your whole component is grounded on its chasis and run the ground wire to that? I may be wrong here, of course, and I'm not an EE...
