In Reply to: another slate garrard plinth review posted by J.D. on April 19, 2007 at 13:34:11:
i read about using the VTAF on a Garrard table to decouple the arm. The slate deck is using decoupling as well in a different manner. The way that decoupling works in these two instances is not on a separate pod but on the same platform so that micro-movements are similar or in unison or something like that. [i am not pretending i know anything - this is improvisation]I have been worrying over how to build a plinth for my TD-111 because I need a template for where the table drops in. There is a lip that the table fits into and no template is "out there" so I just hit on the idea of removing the top layer of the original plinth and using it on a larger lower plinth. ta da.

TD-111 template ... well, yeah !? What better template for a td111 cut-out than the cut-out that the td111 is sitting in already.So now you've got the choice of whether you want to use the old wooden top-deck you've got or go with new materials.

Lotsa opinions re arm mounting...
Because it hides motor rumble and other non-signal info, a decoupled mount is chosen by those who ... okay, I'm saying it-- would like to deceive themselves about the vibrational nasties at large in their turntable's transport section.
Like if you put the roadies on the second bus you can still claim your rock band is a class operation.
I say it's only hiding the problem. Here's a post from recently...:
http://db.audioasylum.com/cgi/m.mpl?forum=vinyl&n=642459Seems to me you can spend time and energy working out the 'separated tonearm support' thing, or spend it just working out a quieter motor and drivetrain.
Leftover time and energy could even be spent on a nice 'modular' arm-board system. Hard-coupled of course.The problem creeps in due to the fact that these idlers are all vintage, no-replacement-parts situations. If a diyer is stuck with an unruly motor or idler mechanism or spindle bearing -- and no replacement parts / or overseas shipping or predatory pricing or both for parts -- very often the only apparent solution left open is to fix the symptom, not the cause, by decoupling the armboard.
Bear in mind that a decoupled armboard only softens the contact at that given point , ie the arm-mount. It does nothing at all for Platter-RecordGroove-Stylus transferred noise and rumble, which will still be bothersome.... because the problem never was the arm-mount in the first place.
Whoof.
Why it is that Pete's arm thing Wriggles, I could never tell you.There are those who might like to argue all that. I'm not one of them. To me, it's an open & shut case.

( also, having spoken with one of the uk slatedeck guys, I'm encouraged to know that he grants that there is a range of customer thinking btwn arm hard-coupled to de-coupled ... all of which he'd like to be able to accomodate with his plinths... so he offers varying kinds of arm mount strategies, though leaning himself--- wait for it -- toward 'coupled'..... )

ok. so i build two armboards. one for the directly coupled arm and another for the VTAF + arm. - just to see. Ultimately I can leave that VTAF on the pseudo-Rega.Or, really, just get another arm.
Thanks for the reply.
It works so well on the NAD ... and I guess that tells us something. ;-)
Exactly. The same also applies to a new turntable, in my opinion. If it is noisy, make it not noisy. Putting a blanket over it only hides the problem.
