    Rickey I made my own fluid damper same principle as the KAB.
    In my case it worked very well on the std techie arm.
    I have my prototype here if you fancy some DIY/ play with it (and some thick silicon fluid) before making a major spend.

    Indeed, I'd fancy a look at that

    We have done so much for so long with so little, we are now qualified to do anything with nothing.

    In case anyone wanted to experiment with this, here is a pic of what it looks like. The caulk is the stuff that comes in a squeeze tube used to seal around sinks & tubs. I used the edge of a credit card to remove the excess and smooth it out some. Yes, it could be neater but it's hidden in use so I don't worry about it.

    And... somehow? That load of goop.. doesn't ruin the platter's balance ?

    I think there's an equally sized load of goop on the other side, to make it all work out.

    That said, the -1200 never had a balanced platter, that was reserved for the SP's. Also, the Techincs rubber damper was just glued in at the factory; only manufacturing tolerances kept it centered, and remember we're talking about glue and rubber.

    I've had some at-length conversations with people who have filled their platters with lead and glued (epoxy) it in, and a guy who has just filled the inside with a never-gets-completly-hard epoxy, and in all cases they have not reported any issues with balance. It's just not an issue if you take rudimentary precautions to keep it from getting grossly off-balance.

    Cool The "Goop Mod"

    Don't forget that the goop is applied to the entire channel around the underside of the platter

    The stock Techie platter makes a right nice gong. Just hold it by one of the finger holes and strike the rim with a wooden spoon or some such and you'll hear what I'm talking about.

    Maybe someone will do the "Goop Mod" to a stock platter and report back?

    Ever grab a ringing bell or gong by the rim and see how fast the sound stops? That's the principal at work here. Applying a layer of Dynamat Extreme and a bit of goop (tub & tile caulk) absolutely leaves the pitiful damping of the stock undermat in the dust. Does this work as well as a good aftermarket platter? I doubt it, but I spent less than the cost of a good mat for a very good improvement
