Equipment Set-up Recommendations?

Outlier, I almost forgot to add one experience I had. I have Mana stands, level 2, under my tt. I was having footfall problems. Lloyd Walker suggested a brace to the wall from well up on the rack. His argument was that the rack does not go up and down as the floor is anchored at the wall; rather it flexs up and down only in the middle but sways the rack fore and aft near the walls. At any rate, the brace worked. This is an effective solution only if it passes WAF, of course.

John, Make sure the the following steps.
1.Stepping with 3 tip toe under the TT And make sure it will not easy to fall down.
2.Level the TT.
3.Level the tonearm. Adjust the counter weight to balance the cartridge with zero VTF. Then look which direction the arm slide to.Adjust the level cone screw till you get the perfect level.(please keep the cartridge with stylus protect on when you are doing this adjustment).
4.Adjust the tangential (overhang) And give it a approximate VTA now.
5.Adjust the Azimuth.
6.Give the 75% VTF of cartridge's recommend(around 1.5gw).
7.Play some records and make sure everything were well setup already.

There is no fricition between the air bean and slide arm wand when air bearing working. The moving force was gave from the groove of vinyl when turn. Let us think about this. If you do not put the stylus on its right position. what will you get??? Three result.Jump to inside. nothing happan.Jump to outside....

Or If the arm slide without parallel with TT. Yes, 3 result.

Raul, Have you ever been experienced with MG-1?
You are absolutely right. This is not an air tangent.
1.The proto type had been complete on July 2001. The ari tangent announced their 2002 model on Oct 2001. I started to build this arm on Feb 2000 .Did you ever been seen the lathe machine. Yes you are right. The mechnical of MG-1 were base on lathe machine's tool post.
2.Please check the angle of the air beam blow design and level adjust mount design and DRO design between MG-1 and AT's design ( www.airtangent.net http://www.airtangent.net/images/45b.gi ) You will know what I am talking about.
3. I am sorry that I don't even seen the "real" air tangent.
4. I gave the best I have. And share the "real" I have.

If Priced this arm $300.00 USD is a mistake. I think the people will enjoy this mistake as well as I am.

One more thing. I am going to design a TT which will operate by air bearing(experiment complete)with vacuum suck down system. And direct drive mortor....

May I know how much should I ask for to avoid The MG-3 to become to another one well konwn TT's clone...
Thanks for clarify this fact.
Enjoy the music...

Hi John,

the first thing to bear in mind with any TT/tonearm is that the rig has to be perfectly stable - if it is subject to footfalls then it will be very sensitive to feedback which may not be immediatly obvious, however it will adversly affect your sound. So it's clearly critical to have the TT on a stable platform. If you check out http://www.theanalogdept.com/ you'll see pictures of Teres TT's on wall mounts so if you mount the wall mount properly that will overcome the footfall problem.

Now I dont understand why you should have any difference between the MG-1 and the rega in terms of skipping. DO you have the same down force on each arm? You need a gauge to measure down force - a small digital balance is the easiest to use - it would appear that with the rega you have enough down force to compensate for the instability in the stand, - the downfoce needs to be set for the cartidge - first by the manufacturers specs, and then fine tuned by listening. Dont be twmpted to add downforce to stop it skipping - this will wear out your records and your cartidge and it will not sound at it's best.

Hope this helps

Hi Guys:
Thanks for the extra input. All good thoughts. I'll do a little more experimenting over the weekend and see can I dial in settings, levelling and support a bit more. Also, because this is a double stand (supported on six cones), I may try supporting it on just four cones (eliminating the center ones). I called Adona and received this tip - which sounds like a good one. That should make the effective weight at each of the four supports 50% heavier on average, if my reasoning is correct.

Also, Ada, thanks for the good instructions on optimizing the setup. I believe I have the leveling jsut right, althoguh I haven't applied the methodology you suggest above, which should provide me with better accuracy.

Also, for folks who've suggested adding more mass to the stand, the stand itself weights 230lb, which is pretty beefy in my books as is ;-) The platforms of the rack are granite with some type of substane underneath - looks like some concoction of MDF and tar or something? Anyway, supposed to proved close to flat frequency response.

Anyway, will keep you posted. So many of the above commets are invaluable. Thanks guys.
