As I was fiddling with my WTA table set-up while installing a new cart, it occurred to me that it should be possible to help other WTA owners really dial in their turntables by providing some pretty simple precise measurements of the table. I'd love to get the following measurements from users of the WTA who feel that they have it really dialed in, or who had their WTA installed by a dealer that they really trust. I'm not going to post my measurements here yet since I don't have much vinyl experience dialing in a table and don't have the good fortune of having a WTA dealer in town. OK, here is what I think would be very helpful to know:

Height of bearing cup:
Height of tonearm suspension pillar:
Distance from top of bearing cup to silicon gel (with golfball in cup):
Distance from suspension pillar to azimuth collar:
Cartridge installed:
Height from vinyl to bottom of headshell plate:

Yes, there may be tweaking for specific carts, listening preferences, etc that can be done. But having measurements that experiences vinyl heads have settled on will be a great starting point for set-up. These should be easy measurements to take, and these will go a long way to helping WTA owners replicate set-ups that have worked for others.



And Mike Pranka, if you're following this Circle, I'd love to hear your thoughts on this. Providing the measurements of how you have it dialed in would be of great help for those of us without a local Well Tempered dealer who can help with set-up.

One problem for a working database of settings could be the different amount of silicon gel everybody has in his cup...

And the obvious differences in the length of the nylon-string of the suspension too.

But we should give it a try. Maybe supported by some photos of the setup (arm bearing in detail, headshell, arm from the right side of the plinth).

have a nice day anyway

We should know the amount of gel in the cup by measuring from the top of the bearing cup to the top of the silicon.

Won't the nylon string length always be the same?

[bernie_f]

The height of the silicon gel depends of the amount of gel and how deeply the ball is submerged into it. You can adjust the length of the string to a certain degree by removing the little sticks that stick into the ball and setting loose some millimeters of string...

Good points. I wil add distance from top of silicon to top of the silver piece on top of it holding the arm. And maybe just a yes/no question on if the line has been lengthened, since we'd only need a measurement if it had.

I've been thinking about this thread, and while in theory seems quite good, not sure if it will hold up in actual practice.  With obvious characteristic differences in cartridges, some may require more or less damping-- immersion of ball will be different.  Of course if we all used the same cartridge it would work.

Well, that's why I ask about carts too. Sure that will make a difference. But hopefully we can get the thread to a point to where we have a number of precise reports of what works best with certain carts, or certain types of carts. And WTA users have a useful reference for starting points for getting things dialed in.   My thought is this: let's get some data points and see what we can learn from them.

Hello, i would like to know  something about Noise related to the PSU.

I have used the supllied connection between outer sleeve of power connector and earth on the WTA.
There was much less but still some. I think this is because there is no system connected...

I will go this way for my set up:
Get a Test-LP and listen to the thing.
I also look forward to get a new karat.

What i wanted to ask is this:
What is the difference between using the supplied earth connection cable and desoldering some grey cables on the board of the WTA?

[roscoeiii]

phoner,

You may be better off starting a new thread about this issue.

Won't the nylon string length always be the same?

Nope.
Loose production tolerances mean no arm has exactly the same length of filament.
Likewise the accurate placement of those little bits of tube that go into the golfball.

I've come across two Amadeus arms where the above were so different that the arms couldn't be swapped between 'tables without a complete reset of arm pillar and damping pot etc.
