eminent technology 2 setup help

this is a email from Rushton that is very usefull.. Thank you !!!!

The nice thing about a tangential tracking tonearm is that the cartridge
setup is very straight forward. The only alignment tool you need is a
scribed line from the spindle out to the edge of the platter. This is
provided by the plastic alignment card ("stylus reference gauge") I
mentioned in my first post - it came with the arm originally. If you don't
have one, you can make one from cardboard with some care.

Use this scribed line to set the cartridge overhang. The stylus should
track the line all along its length from spindle to outer edge of the
platter. Make the adjusment by extending or contracting the length of the
armtube.

Look at pages 7 and 24 of the manual (as numbered on the page itself) to
see a drawing of this and for a more detailed explanation for using the
gauge.

Once the the right arm tube length (for correct cartridge overhang) is
determined, mark the arm tube with a piece of tape and set the azimuth.

Azimuth is adjusted by rotating the armtube and by twisting the cartridge
body around its mounting screws (if needed). The technique for determining
correct azimuth is the same as with any privoted arm. As you know, the
point is to get the sylus perfectly perpendicular in the groove walls. The
point of mentioning this is to highlight that relying on the the outside
edges of the cartridge body (as done when using the jig Sean mentioned)
can be misleading. The only thing that matters is the alignment of the
stylus in the groove, and stylii and cantilevers can be assembled not in
alignment with the cartridge body.

Do pay attention to the discussion in the manual of "adjustable effective
mass." That will affect the sound of the cartridge/arm combination. The
correct solution varies by cartridge. I used Grado cartridges (TLZ, XTZ
and Reference), and I always found the best sound was with the lighter
counter weights moved as far away from the spindle as possible.

btw,

i am using it with a sota turntable that has a predrilled arm board.

thanks for your help !!!

best regards,

Mike,

Here is a followup to your further question via email to me about the the stylus alignment gauge. Since you have a pre-drilled armboard on your SOTA, you already have one of the biggest issues solved. The rest is purely an exercise in logic once you understand the principles of the arm design, which I think you do.

The stylus reference gauge is very simple. It is only apiece of plastic with a hole drilled at one end to fit over the spindle and a line scribed from the center of that hole to the end of the piece of plastic. The value of this tool is that you can very gently lower the stylus onto the stylus gauge at various points along its length to check that the stylus is settling right onto the line at each point along the length. Once you accomplish this, you know the arm is tracking perfectly tangential to the groves -- its "in alignment."

Wally Malewicz (of "Wallytractor" fame) makes an alignment gauge for linear tracking toneams. Lloyd Walker includes one with each of his Walker Proscenium Gold turntables, which use a linear tracking arm. You could probably order one from Music Direct, see http://www.amusicdirect.com/products/detail.asp?sku=AWALTRACTOR, but the cost is $149 and you'll probably have to wait for Wally to make one for you. OTOH, you could call Lloyd Walker to see if he has one on hand that he'd sell to you. (http://www.walkeraudio.com) The advantage of the Wallytractor is that the lines are scribed on a reflective surface that makes checking for stylus placement much easier, and it also gives you a great tool for adjusting azimuth by eye when you get to that point. The Wallytractor is beautifully and very accurately made.

Cheaper alternatives may be available. In a quick web search just now I found the following: http://www.turntablebasics.com/index.html It is shown with a pivoted arm, but the line you see drawn from the spindle to the edge should work just fine for what you need to do. Also gives you a mirrored surface.

For $5, this Garrott Brothers Cartridge Protractor would probably work: http://shopping.netsuite.com/s.nl/c.ACCT106601/sc.9/category.-109/it.A/id.1108/.f

Now, here's the least cost alternative... Make your own. Take a piece of heavy stock paper (24lb or greater). Fold the paper exactly in half - lengthways by aligning the edges. Make it a sharp crease. At one end, use scissors to cut off a corner from the end of the folded edge. Unfold the paper and fold it back the other way - to make it lay flat. Your corner cut will now be a "V" at the end of the crease remaining from your fold. Set the "V" against your spindle and the crease should run from the center of the spindle to the outer edge of the platter. Bingo - you now have a stylus alignment gauge with the crease as your scribed line.

Hope this is helping some. It will be confusing the first time through, but hopefully it will get clearer as you work with it.
