mm. THE REGA BAERWALD ARC PROTRACTOR download this protractor at: designed by seb donate to his paypal account. Free Protractor To Align Your Turntable Cartridge! Baerwald, Stevenson, and others came along later, and each published alignment geometry equations. I did my best with the included protractor to align the cart properly, but the Technics doesn’t quite use a Baerwald alignment. I wound up with.

The graph is a visual representation of the columns of numbers on the left, which are a function of three specific tonearm parameters, effective length, angular offset, and stylus overhang as displayed in the tan colored cells, A3, B3, and C3.

The method is different. To adjust Zenith angle, the cartridge body is rotated within the headshell until a parallel alignment exists between the cantilever and the grid lines on the protractor.

Your name or email address: Videos Enjoy the Music. That is my point. The one referenced here: Phil Elliott likes this. Ben AdamsJan 29, You proractor ask “Solver” to find new innermost and outermost groove radii that would yield Steven’s alignment null-points, and you would also get a baerwadl representation of Steven’s tracking error and distortion curves.

I need to fix the alignment on my M97xE. That is our overhang adjustment using a two point protractor. The graph and the rest of the spreadsheet are controlled by inputs to cells A3, B3, and C3 only. These are also spreadsheet input cells, but initially they are linked to the corresponding calculator cells, I3, O3, and Q3 so the calculator controls the entire spreadsheet.

When I tried then on my old TT I seemed to get close but never perfect so the needle would drop in both points while remaining aligned in the grid.

The red wire for the right channel on that headshell wasn’t looking all that well. I did my best with the included protractor to align the cart properly, but the Technics doesn’t quite use a Baerwald alignment. Log in or Sign up.


I was first sent a defective cartridge so I got two opportunities to set it up. It takes time and patience to get it just right, but the results are worth it! You rotate the gauge and the swing the arm until it is.

In the original, generic, headshell, I noticed the right channel had gone nearly nonexistent. Stage has shifted a little more left than I’d like instead of more right like beforeand very weak and muffled. Why does every one of these alignment instructions always contain baerdald wrong statement to confuse the beginner? They are the three yellow cells, I3, J3, and K3 in the calculator at the top of each page, and the three tan cells, A3, B3, and C3, which control the graph and the rest of the spreadsheet.

This will involve some averaging of the zenith angle between the two points, but the stylus should find exact center over both null points. The default or initial input values are Stopped using the stabilizer, no difference.

To adjust overhang, we must adjust the mounting length between the stylus and tonearm pivot. One reason for unlinking the calculator might be to evaluate a tonearm’s bxerwald by inputting effective length, angular offset, and stylus overhang directly into cells A3, B3, and C3, respectively.

If you have to average the zenith between the two points, you don’t have the overhang correct.

But the goal is to adjust the overhang so that the zenith angle is correct at both null points when the stylus is centered over the null point. DarkAuditJan 31, Morgantown, West by God Virginia. Other types of measuring devices exist but the reader will need to discover these. If you want to see pictures of a Baerwald set-up using the Feickert protractor, try page 2 of this thread.


So, the alignment is right if I am looking at it straight on and the cantilever is in a straight line with the line on the protractor? This is the process that I’ve worked out and it works for me! As always, if you have any questions please feel free to e-mail them to me. The output values change in accordance with the equations listed in the instruction area below the graph when new numbers are entered into any of the yellow input cells. I used the VPI jig and it was quite easy but somewhat tedious.

Danny HollandJan 29, AntaresJan 29, The heads of the screws that came with that cart don’t fit properly in a Technics branded headshell, so I had to reverse them. The second cause might be an incorrect pivot-to-spindle mounting distance. I used a paper Baerwald protractor and played a record all the way through and didn’t notice any distortion at all.

Top baerwadl showing the two points of alignment. This will involve some protrcator of the zenith angle between the two points, but the stylus should find exact center over both null points.

I first became aware of the seemingly precise alignment options last year prior to my VPI TT purchase. Thanks for the correction. Protractog up the mounting screws firmly then double check your alignment using the protractor. The first cause might be inadequate room in the slots.

To adjust mounting length, loosen the fasteners ‘just enough’ to allow the cartridge to be slid in either direction within the headshell until the stylus is centered over the null point. Right click your mouse on the link above and choose Save Target A s Where did you get that?
