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.

Danny HollandJan 28, This will involve some averaging of the zenith angle between the two points, but the stylus should find exact center over both null points.

Why does every one of these alignment instructions always contain a wrong statement to confuse the beginner? One reason for unlinking the calculator might be to evaluate a tonearm’s geometry by inputting effective length, angular offset, and bserwald overhang directly into cells A3, B3, and C3, respectively. For one example of a gage that measures ‘pivot to spindle’, link here. And if you have to average the the protractlr between the two points, you don’t have the overhang set right.

Using the VPI jig I only have to deal with the one alignment grid much easier than the 2 point protractors. There are many ways “Solver” can be used to enhance and expand the capabilities of complex spreadsheets.


Any tips on how I can get this right without tearing my hair out or driving the 75 miles back to Pittsburgh and asking the repair guy I bought it from to fix my mess? I laid a straightedge down on the grid to help me gain a better perspective.

As with potractor overhang adjustment, leave the fasteners just slack enough to make the rotation but snug enough to hold position. Guy at the shop double-checked the wire connections, but said without the TT as well, he couldn’t check the alignment. 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. Where did you get that?

About a month ago I broke off the cantilever stupid me. Sounds so much better on the D2 than the M97xE I’m fighting with now. Stage has shifted a little more left than I’d like instead of more right like beforeand very weak and muffled.

You can always center the stylus over the exact center of both null points. 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?

To adjust overhang, we must adjust the mounting length between the stylus and tonearm pivot. It was pre-mounted for a Technics alignment. The graph and the rest of the spreadsheet are controlled by inputs to cells A3, B3, and C3 only.

It is based upon the Baerwald calculations for minimum tracking error when using a pivoted tonearm.


This has been an interesting topic for me. However, if the protractor is paper, you may have to settle for aligning the cartridge body sides parallel to the grid since it will not be possible to get a visual fix between the grid and the cantilever.

This will involve some averaging of the zenith angle between the two points, but the stylus should find exact center over both null points. This is the process that I’ve worked out and it works for me! Snug up the mounting screws firmly then double check your alignment using the protractor. I prefer to use the Baerwald alignment whenever I can for its slightly lower baerwalr error values, however if it becomes necessary, a different protractor orotractor be needed with some combinations of tonearms and cartridges.

Stopped using the stabilizer, no difference. Do you already have an account? Yes, my password is: I recommend that this very important mounting distance, pivot-to-spindle, is checked and compared to the tonearm manufactures specification. For advanced spreadsheet users, the Excel “Solver” function is a very powerful tool that can be used advantageously with this spreadsheet. I ordered the Technics overhang gauge, and printed out the Technics protractor from Vinyl Engine.

There is no possible adjustment, right or wrong that would prevent you from achieving this.
